Plots the significance distribution of clustercluster or segmentsegment
overlap statistics provided by clusterCluster
or
segmentJaccard
, where the a whiteblack gradient is
calculated from log(p)
, and the text shows the overlap statistics,
i.e., the number of overlapping features for clusterCluster
,
or the Jaccard index for segmentJaccard
. Note that two
distinct pvalue cutoffs can be visualyized: pvalues <=p.min
are shown in black, and pvalues p.txt
are shown in white instead
of black text (thus becoming visible on the black of significant
overlaps).
