The RSEG software package is aimed to analyze ChIP-Seq data, especially for identifying genomic regions and their boundaries marked by diffusive histone modification markers, such as H3K36me3 and H3K27me3. It can work with or without control sample. It can be used to find regions with differential histone modifications patterns, either comparsion between two cell types or between two kinds of histone modifications.
