RaceID algorithm

RaceID is a clustering algorithm for the identification of cell types from single-cell RNA-sequencing data. It was specifically designed for the detection of rare cells which correspond to outliers in conventional clustering methods. The package contains RaceID3, the most recently published version of this algorithm, and StemID2, an algorithm for the identification of lineage trees based on RaceID3 analysis. RaceID3 utilizes single cell expression data, and was designed to work well with quantitative single-cell RNA-seq data incorporating unique molecular identifiers. It requires a gene-by-cell expression matrix as input and produces a clustering partition representing cell types. StemID2 assembles these cell types into a lineage tree.


After downloading and unzipping


it can be installed from the command line by

R CMD INSTALL RaceID3_StemID2_package-master

or directly in R from source by

install.packages("RaceID3_StemID2_package-master",repos = NULL, type="source")

(if R is started from the directory where has been downloaded to; otherwise specify the full path)

Alternatively, install in R directly from github using devtools:
