Nucleotide probabilities (in order A,C,G,T) computed over Drosophila dmel40 genome release: 1-strand, 2-strand.
Bergman set has two PWMs for Dl factor. We used dl-A motif becase it shows better quality in all of the cases. PWM ROC curves graph can be found here.
Noyes set containts two sequence-sets for Bcd factor. We took the one corresponding to the better quality motif. The other one is actually presented in the Noyes_hd set.
All 'ready'-motifs logos in comparison sheets are scaled according to the total footprints number (not counting the small number of absent sites). It has no real effect on visual representation.
