Web15.4.2 Step 2. Identify Correlated TF Motifs and TF Gene Score/Expression. To identify TFs whose motif accessibility is correlated with with their own gene activity (either by gene score or gene expression), we use the correlateMatrices() function and provide the two matrices that we are interested in, in this case the GeneScoreMatrix and the MotifMatrix. 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 … WebAug 21, 2024 · Single cell ATAC-seq (scATAC) yields sparse data that makes application of conventional analysis approaches challenging. We developed chromVAR, an R package for analyzing sparse chromatin accessibility data by estimating gain or loss of accessibility within peaks sharing the same motif or annotation while controlling for technical biases. … phil hemingway for supervisor
