DENBStatPermut4GSEA: Calculate NB-statistics quantifying DE for each gene in the...

Description Usage Arguments Value Note Author(s) References See Also Examples

Description

Calculate NB-statistics quantifying differential expression for each gene in the permutation data sets. The results will be used for GSEA run.

Usage

1
DENBStatPermut4GSEA(DEG, permuteMat)

Arguments

DEG

a CountDataSet object, can be the output of runDESeq.

permuteMat

a permutation matrix generated by genpermuteMat.

Value

A matrix of NB-statistics. Each row corresponds to each gene, and each column to each permutation.

Note

The results with the output of DENBStat4GSEA can also be used to run DEpermutePval.
