A fully Bayesian hidden Ising model for ChIP-seq data analysis.
Chromatin immunoprecipitation followed by next generation sequencing (ChIP-seq) is a powerful technique that is being used in a wide range of biological studies including genome-wide measurements of protein-DNA interactions, DNA methylation, and histone modifications. The vast amount of data and biases introduced by sequencing and/or genome mapping pose new challenges and call for effective met...
متن کاملHierarchical hidden Markov model with application to joint analysis of ChIP-chip and ChIP-seq data
MOTIVATION Chromatin immunoprecipitation (ChIP) experiments followed by array hybridization, or ChIP-chip, is a powerful approach for identifying transcription factor binding sites (TFBS) and has been widely used. Recently, massively parallel sequencing coupled with ChIP experiments (ChIP-seq) has been increasingly used as an alternative to ChIP-chip, offering cost-effective genome-wide coverag...
متن کاملChIP-chip: data, model, and analysis.
ChIP-chip (or ChIP-on-chip) is a technology for isolation and identification of genomic sites occupied by specific DNA-binding proteins in living cells. The ChIP-chip signals can be obtained over the whole genome by tiling arrays, where a peak shape is generally observed around a protein-binding site. In this article, we describe the ChIP-chip process and present a probability model for ChIP-ch...
متن کاملStarr: Simple Tiling ARRay analysis for Affymetrix ChIP-chip data
Starr is an extension of the Ringo [6] package for the analysis of ChIP-chip projects. Whereas the latter is specialized to the processing of Nimblegen and Agilent arrays, the former provides all corresponding features for Affymetrix arrays. Data can be read in from Affymetrix CEL-files, or from text files in gff format. Standard quality assessment and data normalization tools are available. St...
متن کاملAn integrated workflow for analysis of ChIP-chip data.
Although ChIP-chip is a powerful tool for genome-wide discovery of transcription factor target genes, the steps involving raw data analysis, identification of promoters, and correlation with binding sites are still laborious processes. Therefore, we report an integrated workflow for the analysis of promoter tiling arrays with the Genomatix ChipInspector system. We compare this tool with open-so...
