getDS: Extract lists of significant isoforms from Differentially...

In maSigPro: Significant Gene Expression Profile Differences in Time Course Gene Expression Data

Description

getDS creates lists of significant isoforms from Differentially Spliced Genes (DSG)

Usage

  getDS(Model, vars="all", rsq=0.4)

Arguments

Model	a IsoModel object
vars	argument of the get.siggenes function applied to isoforms
rsq	cut-off level at the R-squared value for the stepwise regression fit. Only isoforms with R-squared more than rsq are selected

Details

There are 3 possible values for the vars argument: "all", "each" and "groups". See get.siggenes.

Value

In the console a summary of the selection is printed.

Model	a IsoModel object to be used in the following steps
get2	a get.siggenes object to be used in the following steps
DSG	Names of the selected genes: Differentially Spliced Genes
DET	Names of the selected Isoforms: Differentally Expressed Transcripts
List0	a list with the names of Differentially Spliced Genes without Isoforms with R-squared higher than rsq
NumIso.by.gene	Number of selected Isoforms for each Differentially Spliced Gene
