In ctlab/fgsea: Fast Gene Set Enrichment Analysis

Example of expression values obtained for GSE14308.

Description

Expression data was obtained by preprocessing the GSE14308 dataset. For the matrix of gene expression value, the following steps were performed:

• expression values were log2-scaled

• quantile-type normalization was perfomred between arrays

• rows were collapsed by 'ENTREZID'

• rows were sorted in descending order by mean expression value per gene

• finally, top-10_000 genes were taken

The exact script is available as system.file("gen_gse14308_expression_matrix.R", package="fgsea")
