These PWMs were used for all analyses in main text figures. For Figures S2–5 and S13 a smaller set of motifs from the JASPAR CORE database 2016 were used23. For Figure S14, motifs downloaded from http://homer.ucsd.edu/homer/custom.motifs were used24, and for Figure S15 motifs downloaded from http://compbio.mit.edu/encode-motifs/ were used25 in order to use the same motifs as the original publication for those data sets.
