openpipelines 2.x.x (Unreleased)

BREAKING CHANGES

Added cell multiplexing support to the from_cellranger_multi_to_h5mu component and the cellranger_multi workflow. These components now output multiple .h5mu files. The output and output_h5mu arguments respectively now require a value containing a wildcard character *, which will be replaced by the sample ID to form the final output file names . Additionally, a sample_csv argument is added to the from_cellragner_multi_to_h5mu component which describes the sample name per output file (PR #803).
demux/bcl_convert: update BCL convert from 3.10 to 4.2 (PR #774).
demux/cellranger_mkfastq, mapping/cellranger_count, mapping/cellranger_multi and reference/build_cellranger_reference: update cellranger to 8.0.1 (PR #774 and PR #811).

openpipelines 1.0.3

BUG FIXES

qc/calculate_qc_metrics: increase total counts accuracy with low precision floating dtypes as input layer (PR # , backported from PR #852).

openpipelines 1.0.2

BUG FIXES

dataflow/concatenate_h5mu: fix writing out multidimensional annotation dataframes (e.g. .varm) that had their data dtype (dtype) changed as a result of adding more observations after concatenation, causing TypeError. One notable example of this happening is when one of the samples does not have a multimodal annotation dataframe which is present in another sample; causing the values being filled with NA (PR #842, backported from PR #837).

openpipelines 1.0.1

BUG FIXES

Bump viash to 0.8.6 (PR #816, backported from #815). This changes the at-runtime generated nextflow process from an in-memory to an on-disk temporary file, which should cause less issues with Nextflow Fusion.

openpipelines 1.0.0-rc6

BUG FIXES

dataflow/concatenate_h5mu: fix regression bug where observations are no longer linked to the correct metadata after concatenation (PR #807)

openpipelines 1.0.0-rc5

BUG FIXES

rna_singlesample: fixed a bug where selecting the column for the filtering with mitochondrial fractions using obs_name_mitochondrial_fraction was done with the wrong column name, causing ValueError (PR #743).
Fix publishing in process_samples and process_batches (PR #759).

NEW FUNCTIONALITY

dimred/tsne component: Added a tSNE dimensionality reduction component (PR #742).

openpipelines 1.0.0-rc2

BUG FIXES

openpipelines 1.0.0rc1

BREAKING CHANGES

Change separator for arguments with multiple inputs from : to ; (PR #700 and #707). Now, all arguments with multiple: true will use ; as the separator. This change was made to be able to deal with file paths that contain :, e.g. s3://my-bucket/my:file.txt. Furthermore, the ; separator will become the default separator for all arguments with multiple: true in Viash >= 0.9.0.
This project now uses viash version 0.8.4 to build components and workflows. Changes related to this version update should be mostly backwards compatible with respect to the results and execution of the pipelines. From a development perspective, drastic updates have been made to the developemt workflow.

Development related changes:
- Bump viash version to 0.8.4 (PR #598, PR#638 and #706) in the project configuration.
- All pipelines no longer use the anonymous workflow. Instead, these workflows were given a name which was added to the viash config as the entrypoint to the pipeline (PR #598).
- Removed the workflows folder and moved its contents to new locations:
  1. The resources_test_scripts folder now resides in the root of the project (PR #605).
  2. All workflows have been moved to the src/workflows folder (PR #605). This implies that workflows must now be build using viash (ns) build, just like with components.
  3. Adjust GitHub Actions to account for new workflow paths (PR #605).
  4. In order to be backwards compatible, the workflows folder now contains symbolic links to the build workflows in target. This is not a problem when using the repository for pipeline execution. However, if a developer wishes to contribute to the project, symlink support should be enabled in git using git config core.symlinks=true. Alternatively, use git clone -c core.symlinks=true git@github.com:openpipelines-bio/openpipeline.git when cloning the repository. This avoids the symlinks being resolved (PR #628). 4bis. With PR #668, the workflows have been renamed. This does not hamper the backwards compatibility of the symlinks that have been described in 4, because they still use the original location which includes the original name. * multiomics/rna_singlesample has been renamed to rna/process_single_sample, * multiomics/rna_multisample has been renamed to rna/rna_multisample, * multiomics/prot_multisample became prot/prot_multisample, * multiomics/prot_singlesample became prot/prot_singlesample, * multiomics/full_pipeline was moved to multiomics/process_samples, * multiomics/multisample has been renamed to multiomics/process_batches, * multiomics/integration/initialize_integration changed to multiomics/dimensionality_reduction, * finally, all workflows at multiomics/integration/* were moved to integration/*
  5. Removed the workflows/utils folder. Functionality that was provided by the DataflowHelper and WorkflowHelper is now being provided by viash when the workflow is being build (PR #605).
End-user facing changes:
- The concat component had been deprecated and will be removed in a future release. It's functionality has been copied to the concatenate_h5mu component because the name is in conflict with the concat operator from nextflow (PR #598).
- prot_singlesample, rna_singlesample, prot_multisample and rna_multisample: QC statistics are now only calculated once where needed. This means that the mitochondrial gene detection is performed in the rna_singlesample pipeline and the other count based statistics are calculated during the prot_multisample and rna_multisample pipelines. In both cases, the qc pipeline is being used, but only parts of that workflow are activated by parametrization. Previously the count based statistics were calculated in both the singlesample and multisample pipelines, with the results from the multisample pipelines overwriting the previous results. What is breaking here is that the qc statistics are not being added to the results of the singlesample worklows. This is not an issue when using the full_pipeline because in this case the singlesample and multisample workflows are executed in-tandem. If you wish to execute the singlesample workflows in a seperate manner and still include count based statistics, please run the qc pipeline on the result of the singlesample workflow (PR #604).
- filter/filter_with_hvg has been renamed to feature_annotation/highly_variable_features_scanpy, along with the following changes (PR #667).
  - --do_filter was removed
  - --n_top_genes has been renamed to --n_top_features
- full_pipeline, multisample and rna_multisample: Renamed arguments (PR #667).
  - --filter_with_hvg_var_output became --highly_variable_features_obs_batch_key
  - --filter_with_hvg_obs_batch_key became --highly_variable_features_var_output
- rna_multisample: Renamed arguments (PR #667).
  - --filter_with_hvg_n_top_genes became --highly_variable_features_n_top_features
  - --filter_with_hvg_flavor became --highly_variable_features_flavor
Renamed obsm_metrics to uns_metrics for the cellranger_mapping workflow because the cellranger metrics are stored in .uns and not .obsm (PR #610).

MAJOR CHANGES

mapping/cellranger_mkfastq: update from cellranger 6.0.2 to 7.0.1 (PR #675)

NEW FUNCTIONALITY

multisample pipeline: This workflow now works when provided multimple unimodal files or multiple multimodal files, in addition to the previously supported single multimodal file (PR #606). The modalities are processed independently from each other:
- As before, a single multimodal file is split into several unimodal MuData objects, each modality being stored in a file.
- (New) When multiple unimodal files are provided, they can be used used as is.
- (New) Mosaic input (i.e. multiple uni- or multimodal files) are split into unimodal files. Providing the same modality twice is not supported however, meaning the modalities should be unique. For example, using input: ["data1.h5mu", "data2.h5mu"] with data1.h5mu providing data for rna and atac and data2.h5mu for rna and prot will not work, because the rna modality is present in both input files.
multisample workflow: throw an error when argument values for the merge component or the initialize_integration workflow differ between the inputs (PR #606).
Added a split_modalities workflow in order to split a multimodal mudata files into several unimodal mudata files. Its behavior is identical to the split_modalities component, but it also provides functionality to make sure everything works when nextflow's -stub option is enabled (PR #606).
All workflow now use dependencies to handle includes from other workflows (PR #606).
qc/calculate_qc_metrics: allow setting the output column names and disabling the calculation of several metrics (PR #644).
rna_multisample, prot_multisample and qc workflows: allow setting the output column names and disabling the calculation of several metrics (PR #606).
cluster/leiden: Allow calculating multiple resolutions in parallel (PR #645).
qc/calculate_qc_metrics: allow setting the output column names and disabling the calculation of several metrics (PR #644).
rna_multisample workflow: added --modality argument (PR #607).
multisample workflow: in addition to using multimodal files as input, this workflow now also accepts a list of files. The list of files must be the unimodal equivalents of a split multimodal file. The modalities in the list must be unique and after processing the modalities will be merged into multimodal files (PR #606).
Added filter/intersect_obs component which removes observations that are not shared between modalities (PR #589).
Re-enable convert/from_h5mu_to_seurat component (PR #616).
Added the gdo_singlesample pipeline with basic count filtering (PR #672).
process_samples pipeline: the --rna_layer, --prot_layer and gdo_layer argument can not be used to specify an alternative layer to .X where the raw data are stored. To enable this feature, the following changes were required:
- Added transform/move_layer component.
- filter/filter_with_scrublet: added --layer argument.
- transform/clr: added --input_layer argument.
- metadata/grep_annotation_column: added --input_layer argument.
- rna/rna_singlesample, rna/rna_multisample, prot/prot_singlesample and prot/prot_multisample: add --layer argument.
- process_batches: Added rna_layer and prot_layer arguments.
Enable dataset functionality for nf-tower (PR #701)
Added annotate/score_genes and annotate/score_genes_cell_cycle to calculate scanpy gene scores (PR #703).

correction/cellbender_remove_background: Remove muon as a test dependency (PR #636).
(Automatic testing) Update viashpy to 0.6.0 (PR #665).
integrate/scarches, integrate/scvi, velocity/scvelo and integrate/totalvi: pin jax, jaxlib to <0.4.23 (PR #699).

integrate/totalvi: Enable GPU-accelerated computing, unpin torchmetrics and pin jax, jaxlib to <0.4.23 (PR #699).

BUG FIXES

transform/log1p: fix --input_layer argument not functioning (PR #678).

openpipelines 0.12.0

BREAKING CHANGES

The detection of mitochondrial genes has been revisited in order to remove the interdependency with the count filtering and the QC metric calculation. Implementing this changes involved breaking some existing functionality:

filter/filter_with_counts: removed --var_gene_names, --mitochondrial_gene_regex, --var_name_mitochondrial_genes, --min_fraction_mito and --max_fraction_mito (PR #585).
workflows/prot_singlesample: removed --min_fraction_mito and --max_fraction_mito because regex-based detection detection of mitochondrial genes is not possible (PR #585).
The fraction of counts that originated from mitochondrial genes used to be written to an .obs column with a name that was derived from pct_ suffixed by the name of the mitochondrial gene column. The --obs_name_mitochondrial_fraction argument is introduced to change the destination column and the default prefix has changed from pct_ to fraction_ (PR #585).

NEW FUNCTIONALITY

workflows/qc: A pipeline to add basic qc statistics to a MuData object (PR #585).
workflows/rna_singlesample: added --obs_name_mitochondrial_fraction and make sure that the values from --max_fraction_mito and --min_fraction_mito are bound between 0 and 1 (PR #585).
Added filter/delimit_fraction: Turns an annotation column containing values between 0 and 1 into a boolean column based on thresholds (PR #585).
Added metadata/grep_annotation_column: Perform a regex lookup on a column from the annotation matrices .obs or .var (PR #585).
workflows/full_pipelines: added --obs_name_mitochondrial_fraction argument (PR #585).
workflows/prot_multisample: added --var_qc_metrics and --top_n_vars arguments (PR #585).
Added genetic demultiplexing methods cellsnp, demuxlet, freebayes, freemuxlet, scsplit, sourorcell and vireo (PR #343).

MINOR CHANGES

Several components: bump scanpy to 1.9.5 (PR #594).
Refactored prot_multisample and prot_singlesample pipelines to use fromState and toState functionality (PR #585).

openpipelines 0.11.0

BREAKING CHANGES

Nextflow VDSL3: set simplifyOutput to False by default. This implies that components and workflows will output a hashmap with a sole "output" entry when there is only one output (PR #563).
integrate/scvi: rename model_output argument to output_model in order to align with the scvi_leiden workflow. This also fixes a bug with the workflow where the argument did not function (PR #562).

MINOR CHANGES

dataflow/concat: reduce memory consumption when using --other_axis_mode move by processing only one annotation matrix (.var, .obs) at a time (PR #569).
Update viashpy and pin it to 0.5.0 (PR #572 and PR #577).
convert/from_h5ad_to_h5mu, convert/from_h5mu_to_h5ad, dimred/pca, dimred/umap/, filter/filter_with_counts, filter/filter_with_hvg, filter/remove_modality, filter/subset_h5mu, integrate/scanorama, transform/delete_layer and transform/log1p: update python to 3.9 (PR #572).
integrate/scarches: update base image, scvi-tools and pandas to nvcr.io/nvidia/pytorch:23.09-py3, ~=1.0.3 and ~=2.1.0 respectively (PR #572).
integrate/totalvi: update python to 3.9 and scvi-tools to ~=1.0.3 (PR #572).
correction/cellbender_remove_background: change base image to nvcr.io/nvidia/cuda:11.8.0-devel-ubuntu22.04 and downwgrade MuData to 0.2.1 because it is the oldest version that uses python 3.7 (PR #575).
Several integration workflows: prevent leiden from being executed when no resolutions are provided (PR #583).
dataflow/concat: bump pandas to ~=2.1.1 and reduce memory consumption by only reading one modality into memory at a time (PR #568).

openpipelines 0.10.0

BREAKING CHANGES

workflows/full_pipeline: removed --prot_min_fraction_mito and --prot_max_fraction_mito (PR #451)
workflows/rna_multisample and workflows/prot_multisample: Removed concatenation from these pipelines. The input for these pipelines is now a single mudata file that contains data for multiple samples. If you wish to use this pipeline on multiple single-sample mudata files, you can use the dataflow/concat components on them first. This also implies that the ability to add ids to multiple single-sample mudata files prior to concatenation is no longer required, hence the removal of --add_id_to_obs, --sample_id, --add_id_obs_output, and --add_id_make_observation_keys_unique (PR #475).
The scvi pipeline was renamed to scvi_leiden because leiden clustering was added to the pipeline (PR #499).
Upgrade correction/cellbender_remove_background from CellBender v0.2 to CellBender v0.3.0 (PR #523). Between these versions, several arguments related to the slots of the output file have been changed.

MAJOR CHANGES

Several components: update anndata to 0.9.3 and mudata to 0.2.3 (PR #423).
Base resources assigned for a process without any labels is now 1 CPU and 2GB (PR #518).
Updated to Viash 0.7.5 (PR #513).
Removed deprecated variant: vdsl3 tags (PR #513).

Refactor loggers using setup_logger() helper function (PR #534).
Refactor unittest tests to pytest tests (PR #534).

MINOR CHANGES

Add resource labels to several components (PR #518).
full_pipeline: default value for --var_qc_metrics is now the combined values specified for --mitochondrial_gene_regex and --filter_with_hvg_var_output.
dataflow/concat: reduce memory consumption by only reading one modality at the same time (PR #474).
Components that use CellRanger, BCL Convert or bcl2fastq: updated from Ubuntu 20.04 to Ubuntu 22.04 (PR #494).
Components that use CellRanger: updated Picard to 2.27.5 (PR #494).
interprete/liana: Update lianapy to 0.1.9 (PR #497).
qc/multiqc: add unittests (PR #502).
reference/build_cellranger_reference: add unit tests (PR #506).
reference/build_bd_rhapsody_reference: add unittests (PR #504).

NEW FUNCTIONALITY

Added compression/compress_h5mu component (PR #530).
Resource management: when a process exits with a status code between 137 and 140, retry the process with increased memory requirements. Memory scales by multiplying the base memory assigned to the process with the attempt number (PR #518 and PR #527).
integrate/scvi: Add --n_hidden_nodes, --n_dimensions_latent_space, --n_hidden_layers, --dropout_rate, --dispersion, --gene_likelihood, --use_layer_normalization, --use_batch_normalization, --encode_covariates, --deeply_inject_covariates and --use_observed_lib_size parameters.
filter/filter_with_counts: add --var_name_mitochondrial_genes argument to store a boolean array corresponding the detected mitochondrial genes.

integrate/scvi: Add --obs_labels, --obs_size_factor, --obs_categorical_covariate and --obs_continuous_covariate arguments (PR #496).
Added var_qc_metrics_fill_na_value argument to calculate_qc_metrics (PR #477).
Added multiomics/multisample pipeline to run multisample processing followed by the integration setup. It is considered an entrypoint into the full pipeline which skips the single-sample processing. The idea is to allow a a re-run of these steps after a sample has already been processed by the full_pipeline. Keep in mind that samples that are provided as input to this pipeline are processed separately and are not concatenated. Hence, the input should be a concatenated sample (PR #475).
Added multiomics/integration/bbknn_leiden workflow. (PR #456).
workflows/prot_multisample and workflows/full_pipelines: add basic QC statistics to prot modality (PR #485).

For example CRISPR Guide Capture information if added to the .uns slot of the gdo modality, while Antibody Capture information is added to the .uns slot of prot (PR #494).
Added multiomics/integration/totalvi_leiden pipeline (PR #500).
Added totalVI component (PR #386).
workflows/full_pipeline: Add pca_overwrite argument (PR #511).

neighbors/bbknn: Fix --uns_output, --obsp_distances and --obsp_connectivities not being processed correctly (PR #538).

openpipelines 0.9.0

BREAKING CHANGES

Running the integration in the full_pipeline deemed to be impractical because a plethora of integration methods exist, which in turn interact with other functionality (like clustering). This generates a large number of possible usecases which one pipeline cannot cover in an easy manner. Instead, each integration methods will be split into its separate pipeline, and the full_pipeline will prepare for integration by performing steps that are required by many integration methods. Therefore, the following changes were performed:

workflows/full_pipeline: harmony integration and leiden clustering are removed from the pipeline.
Added initialize_integration to run calculations that output information commonly required by the integration methods. This pipeline runs PCA, nearest neighbours and UMAP. This pipeline is run as a subpipeline at the end of full_pipeline.
Added leiden_harmony integration pipeline: run harmony integration followed by neighbour calculations and leiden clustering. Also runs umap on the result.
Removed the integration pipeline.

The old behavior of the full_pipeline can be obtained by running full_pipeline followed by the leiden_harmony pipeline.

The crispr and hashing modalities have been renamed to gdo and hto respectively (PR #392).
Updated Viash to 0.7.4 (PR #390).
cluster/leiden: Output is now stored into .obsm instead of .obs (PR #431).

NEW FUNCTIONALITY

cluster/leiden and integration/harmony_leiden: allow running leiden multiple times with multiple resolutions (PR #431).

workflows/integration/scvi: Run scvi integration followed by neighbour calculations and run umap on the result (PR #396).
mapping/cellranger_multi and workflows/ingestion/cellranger_multi: Added --vdj_inner_enrichment_primers argument (PR #417).
metadata/move_obsm_to_obs: Move a matrix from an .obsm slot into .obs (PR #431).
integrate/scvi validity checks for non-normalized input, obs and vars in order to proceed to training (PR #429).
schemas: Added schema files for authors (PR #436).
schemas: Added schema file for Viash configs (PR #436).
schemas: Refactor author import paths (PR #436).
schemas: Added schema file for file format specification files (PR #437).
query/cellxgene_census: Query Cellxgene census component and save the results to a MuData file. (PR #433).

MAJOR CHANGES

report/mermaid: Now used mermaid-cli to generate images instead of creating a request to mermaid.ink. New --output_format, --width, --height and --background_color arguments were added (PR #419).
All components that used python as base container: use slim version to reduce container image size (PR #427).

MINOR CHANGES

integrate/scvi: update scvi to 1.0.0 (PR #448)
mapping/multi_star: Added --min_success_rate which causes component to fail when the success rate of processed samples were successful (PR #408).

integrate/scvi: the max_epochs is no longer required since it has a default value (PR #396).
workflows/full_pipeline: fix make_observation_keys_unique parameter not being correctly passed to the add_id component, causing ValueError: Observations are not unique across samples during execution of the concat component (PR #422).
annotate/popv: now sets aprox to False to avoid using annoy in scanorama because it fails on processors that are missing the AVX-512 instruction sets, causing Illegal instruction (core dumped).
workflows/full_pipeline: Avoid adding sample names to observation ids twice (PR #457).

openpipelines 0.7.0

MAJOR CHANGES

Removed bin folder. As of viash 0.6.4, a _viash.yaml file can be included in the root of a repository to set common viash options for the project. These options were previously covered in the bin/init script, but this new feature of viash makes its use unnecessary. The viash and nextlow should now be installed in a directory that is included in your $PATH.

MINOR CHANGES

filter/do_filter: raise an error instead of printing a warning when providing a column for var_filer or obs_filter that doesn't exist.

BUG FIXES

workflows/full_pipeline: Fix setting .var output column for filter_with_hvg.
Fix running mapping/cellranger_multi without passing all references.

Solution was to create a --var_gene_names argument which allows selecting a .var column to check using a regex (--mitochondrial_gene_regex).
dataflow/concat, report/mermaid, transform/clr: Don't forget to exit with code returned by pytest.

openpipeline 0.6.0

NEW FUNCTIONALITY

workflows/full_pipeline: add filter_with_hvg_var_output argument.
dimred/pca: Add --overwrite and --var_input arguments.
tranform/clr: Perform CLR normalization on CITE-seq data.

Added from convert/from_cellranger_multi_to_h5mu component.

MAJOR CHANGES

convert/from_velocyto_to_h5mu: Moved to velocity/velocyto_to_h5mu. It also now accepts an optional --input_h5mu argument, to allow directly reading the RNA velocity data into a .h5mu file containing the other modalities.
resources_test/cellranger_tiny_fastq: Include RNA velocity computations as part of the script.
mapping/cellranger_mkfastq: remove --memory and --cpu arguments as (resource management is automatically provided by viash).

MINOR CHANGES

Several components: use gzip compression for writing .h5mu files.
Default value for obs_covariates argument of full pipeline is now sample_id.
Set the tag directive of all Nextflow components to '$id'.

BUG FIXES

Keep data for modalities that are not specifically enabled when running full pipeline.
Fix many components thanks to Viash 0.6.4, which causes errors to be thrown when input and output files are defined but not found.

openpipeline 0.5.1

BREAKING CHANGES

reference/make_reference: Input files changed from type: string to type: file to allow Nextflow to cache the input files fetched from URL.
several components (except from_h5ad_to_h5mu): the --modality arguments no longer accept multiple values.
Remove outdated resources_test_scripts.
convert/from_h5mu_to_seurat: Disabled because MuDataSeurat is currently broken, see https://github.com/PMBio/MuDataSeurat/issues/9.
integrate/harmony: Disabled because it is currently not functioning and the alternative, harmonypy, is used in the workflows.
dataflow/concat: Renamed --sample_names to --input_id and moved the ability to add sample id and to join the sample ids with the observation names to metadata/add_id
Moved dataflow/concat, dataflow/merge and dataflow/split_modalities to a new namespace: dataflow.
Moved workflows/conversion/conversion to workflows/ingestion/conversion

NEW FUNCTIONALITY

metadata/add_id: Add an id to a column in .obs. Also allows joining the id to the .obs_names.
workflows/ingestion/make_reference: A generic component to build a transcriptomics reference into one of many formats.
integrate/scvi: Performs scvi integration.
integrate/add_metadata: Add a csv containing metadata to the .obs or .var field of a mudata file.

DataflowHelper.nf: Added passthroughMap. Usage:

include { passthroughMap as pmap } from "./DataflowHelper.nf"

workflow {
  Channel.fromList([["id", [input: "foo"], "passthrough"]])
    | pmap{ id, data ->
      [id, data + [arg: 10]]
    }
}

Note that in the example above, using a regular map would result in an exception being thrown, that is, "Invalid method invocation call with arguments".

A synonymous of doing this with a regular map() would be:

workflow {
  Channel.fromList([["id", [input: "foo"], "passthrough"]])
    | map{ tup ->
      def (id, data) = tup
      [id, data + [arg: 10]] + tup.drop(2)
    }
}

| setWorkflowArguments(
  pca: [ "input": "input", "obsm_output": "obsm_pca" ]
  integration: [ "obs_covariates": "obs_covariates", "obsm_input": "obsm_pca" ]
)
| getWorkflowArguments("pca")
| pca
| getWorkflowArguments("integration")
| integration

mapping/cellranger_count: Allow passing both directories as well as individual fastq.gz files as inputs.
convert/from_10xh5_to_h5mu: Allow reading in QC metrics, use gene ids as .obs_names instead of gene symbols.
workflows/conversion: Update pipeline to use the latest practices and to get it to a working state.

MINOR CHANGES

dimred/umap: Streamline UMAP parameters by adding --obsm_output parameter to allow choosing the output .obsm slot.

Switch to Viash 0.6.1.
filter/subset_h5mu: Add --modality argument, export to VDSL3, add unit test.
dataflow/split_modalities: Also output modality types in a separate csv.

BUG FIXES

BREAKING CHANGES

Many components: Renamed .var["gene_ids"] and .var["feature_types"] to .var["gene_id"] and .var["feature_type"].

DEPRECATED

convert/from_10xh5_to_h5ad and convert/from_bdrhap_to_h5ad: Removed h5ad based components.
mapping/bd_rhapsody_wta and workflows/ingestion/bd_rhapsody_wta: Deprecated in favour for more generic mapping/bd_rhapsody and workflows/ingestion/bd_rhapsody pipelines.
convert/from_csv_to_h5mu: Disable until it is needed again.
dataflow/concat: Deprecated "concat" option for --other_axis_mode.

NEW COMPONENTS

graph/bbknn: Batch balanced KNN.
transform/scaling: Scale data to unit variance and zero mean.
mapping/bd_rhapsody: Added generic component for running the BD Rhapsody WTA or Targeted analysis, with support for AbSeq, VDJ and/or SMK.
integrate/harmony and integrate/harmonypy: Run a Harmony integration analysis (R-based and Python-based, respectively).
integrate/scanorama: Use Scanorama to integrate different experiments.
reference/make_reference: Download a transcriptomics reference and preprocess it (adding ERCC spikeins and filtering with a regex).
reference/build_bdrhap_reference: Compile a reference into a STAR index in the format expected by BD Rhapsody.

NEW WORKFLOWS

workflows/ingestion/bd_rhapsody: Added generic workflow for running the BD Rhapsody WTA or Targeted analysis, with support for AbSeq, VDJ and/or SMK.
workflows/multiomics/full_pipeline: Implement pipeline for processing multiple multiomics samples.

NEW FUNCTIONALITY

convert/from_bdrhap_to_h5mu: Added support for being able to deal with WTA, Targeted, SMK, AbSeq and VDJ data.
dataflow/concat: Added "move" option to --other_axis_mode, which allows merging .obs and .var by only keeping elements of the matrices which are the same in each of the samples, moving the conflicting values to .varm or .obsm.

MAJOR CHANGES

Multiple components: Update to anndata 0.8 with mudata 0.2.0. This means that the format of the .h5mu files have changed.
multiomics/rna_singlesample: Move transformation counts into layers instead of overwriting .X.
Updated to Viash 0.6.0.

MINOR CHANGES

velocity/velocyto: Allow configuring memory and parallellisation.
cluster/leiden: Add --obsp_connectivities parameter to allow choosing the output slot.
workflows/multiomics/rna_singlesample, workflows/multiomics/rna_multisample and workflows/multiomics/integration: Allow choosing the output paths.
neighbors/bbknn and neighbors/find_neighbors: Add parameters for choosing the input/output slots.
dimred/pca and dimred/umap: Add parameters for choosing the input/output slots.
dataflow/concat: Optimize concat performance by adding multiprocessing and refactoring functions.
workflows/multimodal_integration: Add obs_covariates argument to pipeline.

BUG FIXES

Several components: Revert using slim versions of containers because they do not provide the tools to run nextflow with trace capabilities.
dataflow/concat: Fix an issue where joining boolean values caused TypeError.
workflows/multiomics/rna_multisample, workflows/multiomics/rna_singlesample and workflows/multiomics/integration: Use nextflow trace reporting when running integration tests.

openpipeline 0.4.1

BUG FIXES

workflows/ingestion/bd_rhapsody_wta: use ':' as a seperator for multiple input files and fix integration tests.

MINOR CHANGES

Several components: pin mudata and scanpy dependencies so that anndata version <0.8.0 is used.
