  • Title: rMAT--an R/Bioconductor package for analyzing ChIP-chip experiments.
    Author: Droit A, Cheung C, Gottardo R.
    Journal: Bioinformatics; 2010 Mar 01; 26(5):678-9. PubMed ID: 20089513.
    Abstract:
    SUMMARY: Chromatin immunoprecipitation combined with DNA microarrays (ChIP-chip) has evolved as a popular technique to study DNA-protein binding or post-translational chromatin/histone modifications at the genomic level. However, the raw microarray intensities generate a massive amount of data, creating a need for efficient analysis algorithms and statistical methods to identify enriched regions. RESULTS: We present a fast, free and powerful, open source R package, rMAT, that allows the identification of regions enriched for transcription factor binding sites in ChIP-chip experiments on Affymetrix tiling arrays. AVAILABILITY: The R-package rMAT is available from the Bioconductor web site at http://bioconductor.org and runs on Linux, MAC OS and MS-Windows. rMAT is distributed under the terms of the Artistic Licence 2.0.
