getDS {maSigPro} | R Documentation

## Extract lists of significant isoforms from Differentially Spliced Genes (DSG)

### 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
