WebA couple of observations are notable from these plots. First, individual TFs show considerable amount of variation in their activity scores across different cell types. For instance, LMPP cells have the highest EGR1 activity score, with a mean activity score of 1.879, suggesting EGR1’s prominent role in the transcriptional regulation of LMPP ... WebThis vignette covers the main function of chromVAR, computeDeviations. Inputs The computeDeviations has two required inputs, object and annotations. The first argument should be a RangedSummarizedExperiment with a counts assay storing the fragment counts per peak (rows) per cell or sample (columns).
