Quality control of the ChIP-seq datasets. A The distribution of base quality scores for ChIP-seq of the indicated histone acetylation marks in C2C12 myoblasts differentiated for 24 h (DM) with proliferating myoblasts as control (GM). B The average GC content of the read signals. C The percentage of reads mapped to the reference genome for each of the histone acetylation marks. D Fingerprint plot presents the cumulative percentage of total reads found in a given percentage of the mappable reference genome. E Scatter plots of ChIP-seq. enrichments. F Shown are the FRiP scores determined by MACS2 and the fragment length in base pairs estimated by autocorrelation analysis
