描述----------Description----------
Dataset of CRC published by Venkatachalam et al. (Identification of candidate predisposing copy number variants in familial and early-onset colorectal cancer patients. Int. J. Cancer, 2010). The dataset contains 30 samples that were hybridized on SNP 250k Affymetrix GeneChip arrays. Raw data are available in GEO with identifier GSE13429.
CRC的数据集出版由Venkatachalam等。 (家族性和早发性大肠癌患者的候选易感副本数变异的鉴定。:诠释。研究癌症,2010)。数据集包含30个单核苷酸多态性250K Affymetrix基因芯片阵列杂交样品。在GEO与标识符GSE13429提供原始数据。

格式----------Format----------
Data were preprocessed by PennCNV tool and discretized by Vega algorithm (Morganella et al. VEGA: variational segmentation for copy number detection. Bioinformatics, 2010) which is available as an R/Bioconductor package at the url (http://www.bioconductor.org/packages/devel/bioc/html/Vega.html). Data are organized as a matrix having a row for each observed aberrant region. Each aberrant region is described by the following columns:<br> Sample Name - Chromosome - Start - End - Num of Markers - CN<br>
数据进行预处理PennCNV工具和离散由维加算法(摩等人的VEGA。:变分割拷贝数检测生物信息学,2010),可在URL(http://www.bioconductor的,这是作为一个R / Bioconductor包。 ORG /包/的devel / bioc / HTML / Vega.html)。作为一个有一排每个观测到的异常区域的矩阵数据的组织。每个异常的区域是由以下几列:参考样品名称 - 染色体 - 开始 - 结束 - 标记的Num - CN的参考描述
