②图中间部分每一条线代表基因集中的一个基因,及其在基因列表中的排序位置,即,本次gene sets里面的基因在本基因的位置。 ③最下面部分展示的是基因与表型关联的矩阵,红色为与第一个表型(MUT)正相关,在MUT中表达高,蓝色与第二个表型(WT)正相关,在WT中表达高。 ④Leading-edge subset:定义其中对Enrichment score...
Gene set enrichment analysis: A knowledge-based approach for interpreting genome-wide expression profiles 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...
Gene Set Enrichment Analysis (GSEA) is an important method for analyzing gene expression data. It is useful for finding biological themes in gene sets, and it can help to increase the statistical power of analyses by aggregating the signal across groups of related genes. In this chapter, we ...

analysis of gene set enrichment. Thus, an option to handle gene sets with additional quantitative attributes was added to ExAtlas. If the box “Use attributes” is checked, then genes with low scores are transiently excluded from the analysis for varying score thresholds until the highest ...
In our case, GSEA is the source of metadata that is represented as Normalized Enrichment Scores (NES) measured for gene sets of interest. Different supervised machine learning methods can be further applied to the metadata to capture the knowledge. Of course, it is of high importance that such...

The plot shows normalized enrichment scores (NES) obtained from GSEA for those cell cycle gene sets with significant enrichment (FWER-adjusted p < 0.05) after GSEA analysis. A positive NES indicates that the gene set is associated with unstressed, tachyzoite parasites, while a negative NES...
