| HP: GeneTrail – advanced gene set enrichment analysis (2008) | |||||||||||||||
Abstract | |||||||||||||||
| We present a comprehensive and efficient gene set analysis tool, called ‘GeneTrail ’ that offers a rich functionality and is easy to use. Our web-based application facilitates the statistical evaluation of high-throughput genomic or proteomic data sets with respect to enrichment of functional categories. GeneTrail covers a wide variety of biological categories and pathways, among others KEGG, TRANSPATH, TRANSFAC, and GO. Our web server provides two common statistical approaches, ‘Over-Representation Analysis ’ (ORA) comparing a reference set of genes to a test set, and ‘Gene Set Enrichment Analysis ’ (GSEA) scoring sorted lists of genes. Besides other newly developed features, GeneTrail’s statistics module includes a novel dynamic-programming algorithm that improves the P-value computation of GSEA methods considerably. GeneTrail is freely accessible at | |||||||||||||||
