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 …

WebMay 26, 2024 · g UMAP projection of scATAC-seq peripheral blood profiles colored by chromVAR TF motif bias-corrected deviations for the indicated factors. All data are aligned and annotated to hg38 reference genome. WebBy default, chromVAR measures the difference in chromatin accessibility for an annotation relative to the expectation if all cells or samples have the same chromatin accessibility profile but differ simply in read depth. Optionally, this expectation can be adjusted. The function computeExpecations can calculate the expectation in alternate ways.

WebThe chromVAR package takes as inputs 1) aligned sequencing reads, 2) chromatin accessibility peaks (derived from either data aggregated across cells or external resources), and 3) a set of chromatin features representing either motif position weight matrices (PWMs) or genomic annotations (Figure 1A,S1). WebApr 5, 2024 · The addMotifAnnotations function was used to determine the motif presence in the peak set from the JASPAR2024 motif dataset. The addDeviationsMatrix function was then used to compute enrichment of TF activity on a per-cell basis across all motif annotations based on chromVAR. Trajectory Analysis

WebJun 15, 2024 · Label transfer was performed by creating a gene activity matrix from the snATAC-seq data, which is a measure of chromatin accessibility within the gene body and promoter of protein-coding genes.
