testlog: Test if log-transformation is necessary.

In shibiaowan/SHARP: hyperfast and accurate single-cell RNA-Seq data clustering

Description

Somtimes log-transformation can boost the clustering performance; however, it is not always the case. By this function, SHARP can automatically determine whether a log-transformation is necessary.

Usage

testlog(scExp, ncells, p, sncells, n.cores)

Arguments

scExp	input single-cell expression matrix
ncells	number of cells in the expression matrix
p	number of reduced dimensions by random projection
sncells	number of cells randomly selected for checking log-transform. By default, sncells = 100

Examples

flag = testlog(scExp)
