MAST

Model-based Analysis of Single-cell Transcriptomics

Installation Instructions

If you have previously installed the package SingleCellAssay you will want to remove it as MAST superscedes SingleCellAssay. (If both MAST and SingleCellAssay are attached, opaque S4 dispatch errors will result.) Remove it with:

 remove.packages('SingleCellAssay')

Then you may install or update MAST with: install.packages('devtools') library(devtools) install_github('RGLab/MAST') # or if you don't have a working latex setup install_github(RGLab/'MAST', build_vignettes=FALSE) vignette('MAST-intro')

New Features

gseaAfterBoot for competitive geneset analysis under variance inflation
