Motif qualities are related to fragment sizes recovered in N-ChIP. (A) The distribution of high-scoring motifs (P < 5 × 10−4) around factor binding sites from N-ChIP experiments. (B) Midpoint plots of small DNA (<80 bp) fragments recovered from N-ChIP experiments around called binding sites. Each site was ranked by motif scores for the respective factors. Fragments from sites with motifs in the top quintile (magenta) and bottom quintile (yellow) of motif scores are displayed. Box plots show quartile distribution of fragment sizes for each group.
