image Gene Set Enrichment Analysis (GSEA) is a computational method that determines whether an a priori defined set of genes shows statistically significant, concordant differences between two biological states (e.g. phenotypes). 用GSEA做富集分析是非常简单的,结
何为功能富集分析? 功能富集分析是将基因或者蛋白列表分成多个部分,即将一堆基因进行分类,而这里的分类标准往往是按照基因的功能来限定的.换句话说,就是把一个基因列表中,具有相似功能的基因放到一起,并和生物学表型关联起来. 何为GO和KEGG? 为了解决将基因按照功能进行分类的问题,科学家们开发了很多基因功能注释数据库,.这其中比较有名的一个就是Gene Ontology(基因本体论,GO)和Kyoto Encyclopedia of Genes and Genomes(京都基因与基因组百科全书,K

关于数据块.副本的介绍,请参考文章<HDFS源码分析之数据块Block.副本Replica>. 一.数据块状态BlockUCState 数据块状态用枚举类BlockUCState来表示,代码如下: /** * States, which a block can go through while it is under construction. * 状态,一个数据块在under construction(即构建)过程中所应有的状态 */ static public enum BlockUCSt
