WebDec 7, 2024 · We can also compute a per-cell motif activity score by running chromVAR. This allows us to visualize motif activities per cell, and also provides an alternative method of identifying differentially-active motifs between cell types. ChromVAR identifies motifs associated with variability in chromatin accessibility between cells. 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.
