BigWig Manipulation

Usage

bigWigCat [options] out.bw in1.bw in2.bw ...

Manual

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

This tool requires data points in the input files as defined in in1.bw in2.bw ... are all non-overlap; otherwise, it throws errors like the following:

Files a.bigWig and b.bigWig overlap, cannot continue!
a.bigWig spans from chr1:0 to chrY:56885526
b.bigWig spans from chr1:0 to chrY:56885526

In these cases, you may find related tools like bigWigMerge or wiggletools helpful.

Required arguments

  • out.bw: the output indexed bigWig file
  • in1.bw in2.bw ...: bigWig files to be merged

Options

  • -itemsPerSlot=N: Number of data points bundled at lowest level. Default 1024.

Notes

  • must use 
    wigToBigWig -fixedSummaries -keepAllChromosomes
    (perhaps in parallel cluster jobs) to create the input files.
  • By non-overlapping we mean the entire span of each file, from first data point to last data point, must not overlap with that of other files.
