low number of TFs

[rojinsafavi]

Hello,

I am using a package called ArchR to do ATACseq analysis. ArchR uses TFBSTools to extract motifs. I noticed there is only 633 TF extracted from Jaspar, but I think the number is much higher (~1200). I was wondering if there is a reason for such a low number? I talked to ArchR developers, and they said they don't do any sort of processing internally, and that I should probably talk to you regarding this matter.

Thank you
