Analysis of big data from aCGH experiments using parallel computing and ff objects

Bioconductor version: Release (3.1)

Analysis and plotting of array CGH data. Allows usage of Circular Binary Segementation, wavelet-based smoothing (both as in Liu et al., and HaarSeg as in Ben-Yaacov and Eldar), HMM, BioHMM, GLAD, CGHseg. Most computations are parallelized (either via forking or with clusters, including MPI and sockets clusters) and use ff for storing data.

Author: Ramon Diaz-Uriarte <rdiaz02 at> and Oscar M. Rueda < at>. Wavelet-based aCGH smoothing code from Li Hsu <lih at> and Douglas Grove <dgrove at>. Imagemap code from Barry Rowlingson <B.Rowlingson at>. HaarSeg code from Erez Ben-Yaacov; downloaded from <>.
