# Hands-On: ChIPseq functional analysis with GREAT
GREAT is a tool GREAT for the functional analysis of cis-regulatory regions. Assigns biological meaning to a set of non-coding genomic regions by analyzing the annotations of the nearby genes. It uses an ORA (Over-Representation analyis) approach. It is useful for peaks identified by any epigenomic profiling technique.
