WebYes, this is possible. In the first step, the summits are computed for all merged peaks in the consensus peakset. Next, the peaks are re-centered around this summit, so will all be of width summits*2+1.If any of these newly re-centered peaks overlap, they will be merged, and hence will be wider than summits*2+1 bp..
