Manual

This tool is part of UCSC Genome Browser's utilities.

wigCorrelate works by finding items that overlap in the different wig or bigwig files. Within the overlap it considers each base a separate observation and calculates Pearson's R based on that. The output is to stdout.

Options

• -clampMax=N: values larger than this are clipped to this value

Example

Use wigCorrelate to calculate pairwise Pearson's $R$ among three bigwig files (a.bw, b.bw, and c.bw):

wigCorrelate a.bigWig b.bigWig c.bigWig

Results like the following will be printed to your screen (the default stdout)

a.bigWig b.bigWig 0.406864
a.bigWig c.bigWig 0.455641
b.bigWig c.bigWig 0.591586
