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. 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.
