Many coding genes are well annotated with their biological functions. Non-coding regions typically lack such annotation. GREAT , the Genomic Regions Enrichment of Annotations Tool, assigns biological meaning to a set of non-coding genomic regions by analyzing the annotations of the nearby genes. Thus, it is particularly useful in studying cis functions of sets of non-coding genomic regions. The Bejerano Lab developed GREAT and hosts the GREAT web server Cis-regulatory regions can be identified via both experimental methods (e.g. chromatin immunoprecipitation followed by massively parallel sequencing) and by computational methods (e.g. sequence conservation in a given clade).
