ChIP Seq Data:

ChIP-Seq peak calling was performed with MACSv2.0.10. Both the standard method for H3K4me3 and H3K27ac and the –broad flag method for H3K4me1, H3K27me3, H3K36me3, H3K4me9 with default parameters were used. All samples were normalized by sequencing depth in million reads. Browser shows treat_pileup.bigWig files and the corresponding peaks.broadPeak or peaks.narrowPeak files.

Chromatin states were learned by applying the ChromHMM hidden Markov Model v1.10. An 11 state model was trained with the full data set. Each time point was segmented using the 11 state model. Browser shows dense view of segmentation for each time point.
