 To help interpretation, we grouped sequence classes into groups including P (Promoter), E (Enhancer), CTCF (CTCF-cohesin binding), TF (TF binding), PC (Polycomb-repressed), HET (Heterochromatin), TN (Transcription), and L (Low Signal) sequence classes. Please refer to our manuscript for a more detailed description of the sequence classes.
