[…] or absence of the mutations within each sample. for the cn data the levels of alteration were categorized as homozygous deletion, loss, unchanged, gain and amplification. the bioconductor package cghregions was used for dimension reduction of the cn alteration matrix, in order minimize the weight of large alterations, and the resulting matrix was used as input for phangorn., representation […]

[…] median absolute deviation (mad) values below 0.4. array-cgh data is deposited in ncbi's gene expression omnibus (geo accession number gse75500)., dimension reduction was achieved by application of “cghregions” (version 1.22.0; setting: averror: 0.015) [] and resulted in 808 cna regions. these regions were subsequently used for two-group comparisons of stage ii versus iii and relapse versus […]

[…] considered lost, modal copy number ≥ ploidy considered gained and modal copy number ≥ ploidy considered amplified. for each case, dimension reduction was performed using the bioconductor package cghregions to generate a matrix of collapsed copy number regions. oncoscan array data have been deposited to the ncbi gene expression omnibus under the accession gse79052., the cancer cell fraction […]

[…] minimum number of 10 consecutive probes. the segmentation process was carried out using the dnacopy bioconductor package []. bioconductor´s cghcall package was employed for determining the step, and cghregions and cghtest packages[] were used to estimate genomic regions and false discovery rate, respectively., microarray and sequencing data have been deposited in geo and sra, under the following […]

DOI: 10.1016/j.ebiom.2015.06.022

[…] estimates of the tumors and matched blood samples. for tumors with no matching blood sample, sex-matched pooled baselines from all blood samples were used to calculate log2-r ratios. cghcall () and cghregions () implementing the dnacopy segmentation algorithm were used to create a reduced segment matrix containing five copy number levels. all parameters used for copy number segmentations […]
