hiHMM Models (R5) (hiHMM_models) Track Description
 

Description

This track shows the results of the joint chromatin state segmentation of the histone modification data for human, D. melanogaster, and C. elegans using hiHMM. The analysis results were lifted from the D. melanogaster Release 5 assembly over to the Release 6 assembly.

This analysis classified each genome into 16 chromatin states. The histone enrichment patterns for each state are shown in Figure 2 of the manuscript by Ho JWK and colleagues. The properties of each state are summarized in the table below:
