描述----------Description----------
A mapping between Human probe-sets and Mouse probe-sets
人类探测器套和鼠标探针集合之间的映射
用法----------Usage----------
data(map.data)
Details
详情----------Details----------
map.data is a list object containing 3 components, probe.map, map.Aprobe.col and map.Bprobe.col. The component probe.map is a data frame with 2 columns of probe-sets identifiers from human and mouse array respectively. This sample mapping data probe.map is a subset of the full mapping data set across human genome U133 Plus 2.0 Array and mouse Expression 430 Array available at www.affymetrix.com. They provide mutiple match mode data sets, such as Good Match, Complex Match Best match etc. We downloaded the Best Match data set as our mapping data. The probe-sets in probe.map are selected such that they are contained in both expression matrix of human.data and mouse.data. Users can choose mapping data according to the species and platforms of their gene expression profiles either by downloading from www.affymetrix.com or from other sources. The array platforms of mapping data must match that of gene expression profile of each species.
map.data是一个列表对象,包含3个组成部分,probe.map,map.Aprobe.col和map.Bprobe.col。在的组件probe.map是一个2列,分别从人类和小鼠阵列探针集标识符的数据框。此示例映射的数据probe.map是一个完整的映射整个人类基因组U133加2.0阵列和鼠标的表达430阵列可在www.affymetrix.com数据集的子集。他们提供的多重比赛模式,如良好的匹配,数据集,复杂的匹配最佳匹配最佳匹配数据设置为我们的图数据下载等。被选中的在probe.map探针集等,他们正在在都表达human.data和mouse.data矩阵所载。根据要么由从www.affymetrix.com或其他来源下载的物种和他们的基因表达谱平台,用户可以选择测绘数据。测绘数据的阵列平台必须匹配,每个物种的基因的表达谱。
probe.map component of the sample data map.data contains 490 rows of ortholog-matched probe-sets across human array and mouse array. map.Aprobe.col and map.Bprobe.col specify column number or name containing the probe-sets from study A and study B respectively.
probe.map样本数据map.data的组件包含490行的同源匹配的探针集在人类阵列和鼠标阵列。 map.Aprobe.col和map.Bprobe.col指定列的编号或名称包含从研究的探针集A和研究B。
