GREAM (Genomic Repeat Element Analyzer for Mammals) is a tool to select, screen, and analyze genomic repeats in mammals that are likely to be important.

GREAM offers the following listings and analyzes:
1. Produce a categorized list of a wide range of statistically over- or under-reperensented repeated elements, and specific types, such as, for example, transposons, retro-transposons.
2. Enrichment within a specied region of a chromosome.
3. comparative distribution across the neighborhood of orthologous genes.
