CELLCode

CellCode

An R package that performs multi-layered differnetial expression analysis to account for tissue composition heterogeneity. It estimates cell-proportions, performs and correction, and assigns trascriptionally regulated genes to the tissue of origin.

Code.

DataRemix

DataRemix

An R package to optimize a data-normalization transform for specific biological tasks.

Code.

intervalStats

A tool to compute associations between genomic interavals such as peaks for a ChIPseq or ATACseq dataset that uses exact enumeration to compute accurate p-values.

Code. Also available as part of the coloc-stats webserver.
