详情----------Details----------
This mouse.data is a subset taken from our published mouse data (Johnson et al. 2010). The original full mouse data was profiled by affymetrix 430 v2(mRNA). It contains 45037 probe-sets for 13 mice brain tumors and 179 normal mice stem cells.
此mouse.data就是从我们公布的鼠标数据(约翰逊等人,2010年)所采取的一个子集。原全鼠标数据是由Affymetrix 430 V2(mRNA)的异形。它包含13小鼠脑肿瘤和179正常小鼠干单元的探针45037套。
We used the best-match data (available from www.affymetrix.com) as the mapping data of ortholog-matched probe-sets across human gene expression data and mouse gene expression data. expr slot of mouse.data is a matrix of subset of the full mouse gene expression data. Those selected mouse probe-sets are ortholog-matched with human probe-sets in human.data. pData slot of the mouse.data is a data frame with row representing mouse samples and two columns indicating sample IDs and sample group labels for each sample (either "mouse.tumor" or "mouse.control").
我们用同源匹配的探针在人类的基因表达数据和小鼠的基因表达数据集的映射数据的最佳匹配数据(从www.affymetrix.com)。 expr的mouse.data槽是一个完整的小鼠基因表达数据的一个子集的矩阵。鼠标的选定探针集同源匹配与人类在human.data探针集。 PDATA mouse.data插槽是代表一行鼠标样品和两列表示每个样品的样品ID和组样品标签(要么的“mouse.tumor”或“mouse.control”)的数据框。
值----------Value----------
参数:expr(mouse.data)
A matrix with 264 rows and 192 columns with rows representing probe-sets and cloumns of mouse sample IDs. Each row name of the matrix is a probe-set Identifier.
一个代表探针台和鼠标样品ID cloumns行与264行和192列的矩阵。矩阵的每一行的名字是一个探针集标识符。
参数:pData(mouse.data)
A data frame with 192 rows and 2 columns. Each row represents one mouse sample. Column id is the mouse sample ID and grp is the assigned sample group label.
一个数据框192行2列。每一行代表一个鼠标样品。列ID是鼠标样品编号和GRP是分配的样本组标签。
