Running chromVAR for a subset of peaks?

[rargelaguet]

Hello,
is it possible to run chromVAR for a subset of peaks? I could create submatrices of PeakMatrix and then run chromVAR for these, but it would be more efficient if one could just specify a subset of peaks as argument to addDeviationsMatrix. Thanks!

This is not currently possible as a parameter but could be done as you suggest using a manual work around. I imagine that if your peakset was X and you had a deviations matrix that was subsetX, this would probably break some downstream ArchR functionalities but I'm not 100% sure. Perhaps @jgranja24 can weigh in.
