Motif analysis of active candidate enhancers using genomic background ( g ) or inactive enhancers as background ( h ). The active enhancers were the union of the candidate regions active in the day 17 and day 24 experiments ( n = 1,185). Motif enrichment P value was calculated by Homer 38 using a binomial distribution and BenjaminiHochberg correction ( Q value). For complete motif analysis results, see Supplementary Data 1 . Data are shown as mean ± s.d. MFI, mean fluorescence intensity.
