C. Box plot depicting the length of exon junctions found differentially regulated by MAJIQ between HP1γ (green) and KO (orange) in three categories as in Fig EV5A, all classified differential HP1γ/KO junctions, annotated alternative exon junctions, non-annotated de novo cryptic junctions detected in KO only; n, differential events. Box boundaries represent 25th and 75th percentiles; center line represents median; whiskers indicate ±1.5×IQR; points are values of outliers. Data information: All graphes represent mean and s.d. (** P < 0.005, ***P < 0.001; two-tailed Student's t-test).
