Description

I am looking for the MACS2 p-value signal for every base-pair, similar to the bigwigs available from ROADMAP or EPIMAP.

Had a discussion with @JoseEspinosa and he thinks it may be available using the --bdg option when calling MACS2 but this is not a parameter that is currently available:

Research direction

Start by reading main.nf around lines 1135-1145 and inspect how MACS2 is currently called. Check how the --bdg option affects MACS2 outputs and how signal files are handled in the workflow. Done means the pipeline can produce bigWig output containing the MACS2 p-value signal for every base pair.
