+### Commands and config
 
 This section describes how the plots in the manuscript (to be added) were generated using scATACpipe. For comparison, the manuscript conducted 3 separate analyses, each using a different preprocessing strategy (`default`, `10xgenomics`, `chromap`). Since the commands and preprocessed results are quite similar across the three methods, only the `chromap` option will be demonstrated here.
 
 1.  The initial execution:
