 The tool first samples indexed BAM files and counts all reads overlapping a window (bin) of specified length.

+These counts are then sorted according to their rank (the bin with the highest number of reads has the highest rank)
+and the cumulative sum of read counts are plotted. An ideal input (control sample) with perfect uniform distribution of reads
+along the genome (i.e. without enrichments in open chromatin etc.) should
 generate a straight diagonal line. A very specific and strong ChIP enrichment will be indicated by a prominent and steep
 rise of the cumulative sum towards the highest rank. This means that a big chunk of reads from the ChIP sample is located in
 few bins which corresponds to high, narrow enrichments seen for transcription factors.
