find

The find program simply examines the bigWig for local extrema or regions above or below thresholds. In terms of peak-finding, it's not very sophisticated. The usage is the following:

bwtool find - find parts of genome that satisfy given constraints
   in the bigWig data.
usage:
   bwtool find <operator> [operator options] input.bw[:chr:start-end] output.bed
operators:
   local-extrema        output is 6-field bedGraph with +/- indicating if the extrema
                        is a local minimum or maximum.
        -min-sep=d      to avoid local clusters of extrema, define a minimum distance
                        they must be separated by (d)
        -maxima         only find local maxima
        -minima         only find local minima
