Scripts for procssing snATAC-seq data

[DylanMannKrzisnik]

Thank you for sharing this resource. Although many of the scripts for processing snRNA-seq data are available, where can we find scripts for snATAC-seq data? Or, what would be the best way to use snATAC-seq data from brainSCOPE and create an ArchRProject?

Thank you for your queries. We have just updated our database to include all the processed snATAC-seq data in our database here: https://doi.org/10.7303/syn51111084.6

We are still working on getting our snATAC-seq pipeline up on Github. Please check back with us later if the above link does not fully meet your needs.

That's great, thank you!

I am particularly interested in the MultiomeBrain data. According to the link you've provided, this data can be retrieved with the facet dataGroup = "ATACseq". However, I cannot see the ATACseq option for the dataGroup facet (see screenshot).

Perhaps it is better to select analysisType = "Processed_snATACseq" instead (also visible in the screenshot)?

Is there a terminal command line solution for accessing the data, and filtering the data by facet?

Much appreciated.

You are very welcome! And yes, it is best to subset things by the "Processed_snATAC" tag. Additionally (that is, by clicking the following as well), you can look under parentID for the specific data types you are looking for.

Correction: I had previously not taken a proper screenshot of the dataGroup facet.

Hi, Please let me know if this has not been resolved.

Thank you for the follow-up.

Indeed, the parentID facet includes the "MultiomeBrain-DLPFC" option which should be helpful. In the end, I will be looking to recreate/load a nuclei x peaks ATAC counts matrix. Once we are granted access to the data via the NRGR application protocol, I will be better able to assess whether the search queries correspond to our needs.
