Bimodal distribution of the HCT count for 273 PWMs with respect to the GC content of HCTs. PWMs with more than 400 HCTs (28.6%, black) have HCTs that are either AT-rich (5.5%) or GC-rich (23.1%). The GC content was calculated for the entire span of the HCT, but avoiding coding and repetitive sequences.
