-# GenErode execution on SLURM clusters
+# GenErode execution on Dardel (PDC/KTH)
 
-With the switch to Snakemake version 8, GenErode can be run 
-the following on SLURM clusters:
-
-1) Create the GenErode conda environment or update an earlier 
-version. The latest conda environment contains the Snakemake 
-executor plugin for slurm:
-
-```
-conda create -f environment.yaml -n generode
-```
-
-2) Copy one of the example configuration files `config/slurm/profile/config_plugin_rackham.yaml` 
-or `config/slurm/profile/config_plugin_dardel.yaml` to 
-`slurm/config.yaml`. This file specifies compute resources 
-for each rule or group jobs. Any rule or group job that is 
-not listed under `set-threads` or `set-resources` uses 
-default resources specified under `default-resources`. If 
-any rule or group jobs fail due to too little memory or run 
-time, their compute resources can be updated in this file. 
-
-> Note that the current configuration files were adjusted to the 
-HPC clusters Rackham from UPPMAX and Dardel from PDC/KTH. Details 
-on how to configure and run GenErode on Dardel are provided below. 
-The configuration file for Snakemake version 7 was kept for comparison 
-which was also written for Rackham/UPPMAX. 
-
-3) Start GenErode the following:
-
-- Open a tmux or screen session
-- Activate the GenErode conda environment
-- Start the dry run:
-
-```
-snakemake --profile slurm -np &> YYMMDD_dry.out
-```
-
-- Start the main run:
-
-```
-snakemake --profile slurm &> YYMMDD_main.out
-```
-
-> Useful flags for running the pipeline: `--ri` to re-run 
-incomplete jobs and `-k` to keep going in case a job fails.
