DNA芯片分析仪(dChip)(www.dchip.org)是一种用于探测级别(例如Affymetrix公司的平台)和高层次的基因表达微阵列和SNP微阵列(李和黄2001年,林等人 2004年分析的Windows软件)。
或从不同的基因表达微阵列平台SNP数据分析,也可以作为外部数据集进口。在探头水平,dChip可以显示和正常化文件,并基于模型的方法使汇集跨多个阵列和自动探头的选择来处理交叉杂交和图像信息的污染。高级别dChip分析包括比较样本,层次聚类,观点表达以及染色体,陆和SNP单核苷酸多态性数据,并复制阵列数量分析,连锁分析。在这些功能基因的信息资料和样品的分析结果与相关性。
DNA芯片分析软件,似乎是两个华人开发的软件。
英文介绍:
DNA-Chip Analyzer (dChip) (www.dchip.org) is a Windows software package for probe-level (e.g. Affymetrix platform) and high-level analysis of gene expression microarrays and SNP microarrays (Li and Wong 2001a, Lin et al. 2004). Gene expression or SNP data from various microarray platforms can also be analyzed by importing as external dataset. At the probe level, dChip can display and normalize the CEL files, and the model-based approach allows pooling information across multiple arrays and automatic probe selection to handle cross-hybridization and image contamination. High-level analysis in dChip includes comparing samples, hierarchical clustering, view expression and SNP data along chromosome, LOH and copy number analysis of SNP arrays, and linkage analysis. In these functions the gene information and sample information are correlated with the analysis results.
