esu JASPAR format. see HOCOMOCO for tf binding models.

HOMER outputs known and de novo motif finding.

use jaspar -- vertebrate, non-redundant individual -- jaspar or MEME format? https://jaspar.genereg.net/downloads/

might need to convert jaspar to homer.motif file. first determine if homer accepts jaspar as-is, otherwise there might be a tool that exists already? https://meme-suite.org/meme/doc/motif_conversion.html
