Chromvar motif activity
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. WebOct 13, 2024 · Differential motif analysis with ChromVAR confirmed high scores for neural progenitor cell–associated motifs, including ASCL1 in CNV + cells ( Fig. 3G ), while the putative nonneoplastic clusters showed increased occupancy at DNA recognition motifs associated with TFs associated with the hematopoietic lineages, such as IKZF1 ( Fig. 3H ).
