Webmotif: Local Pattern Analysis Describes spatial patterns of categorical raster data for any defined regular and irregular areas. Patterns are described quantitatively using built-in … 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.
