usage: islands [options] placefile[s]

Options

-o	Specify the filename to write to.
--out-dir	Specify the directory to write files to.
--prefix	Specify a string to be prepended to filenames.
--pp	Use posterior probability for the weight.
--discard-below

Details

Say that two pqueries overlap if there is an edge such that the two pqueries both put mass on that edge. Define the overlap graph to be the graph with nodes being pqueries and edges signifying overlap. Call the connected components of the overlap graph islands.

That is, islands are maximal sets of pqueries with no edge-mass overlap between sets.
