Chromvar signac
WebchromVAR is an R package for the analysis of sparse chromatin accessibility. chromVAR takes as inputs aligned fragments (filtered for duplicates and low quality) from ATAC-seq or DNAse-seq experiments as well as genomic annotations such as motif positions. chromVAR computes for each annotation and each cell or sample a bias corrected … WebPackage ‘Signac’ ... Compute chromVAR deviations for groups of peaks. The goal of this function is similar to that of AddModuleScore except that it is designed for single-cell chromatin data. The chromVAR devia-tions for each group of peaks will be added to the object metadata.
