We piled up the ATAC reads for all binding sites of a given TF across the genome and plotted read count versus the distance from the centre of the TF motif and the length of each read, producing a characteristic signature of TF accessibility for a given sample, which also encodes the footprint of the TF complex itself, in the cancer (Extended Data Fig. 3A and additional figures at 10.6084/m9.figshare.19857391) and normal (Extended Data Fig. 3B) regions. Here, TF is linked to cancer.
