-          Please note that the CNV spikes are based on the frequency of occurrence of <i>any</i> CNV
-          in a given 1Mb interval, not on their overlap. Some genome bins may have at least one small CNV in
-          each sample - especially in peri-centromeric regions - and therefore will display with a 100% frequency -
-          although many of those may not overlap.
