runModelGeneVar: Calculate Variable Genes with Scran modelGeneVar

In compbiomed/singleCellTK: Comprehensive and Interactive Analysis of Single Cell RNA-Seq Data

Calculate Variable Genes with Scran modelGeneVar

Description

Generates and stores variability data in the input SingleCellExperiment object, using modelGeneVar method.

Also selects a specified number of top HVGs and store the logical selection in rowData.

Usage

runModelGeneVar(inSCE, useAssay = "logcounts")

Arguments

inSCE	A SingleCellExperiment object
useAssay	A character string to specify an assay to compute variable features from. Default "logcounts".

Value

inSCE updated with variable feature metrics in rowData
