Just a heads up that as a side effect of now reporting both the full and pruned RMSD of an iterated match, the number of return values from Midas.match(), Midas.matchXform(), and MatchMaker.match() changed. The first two added the full RMSD just after the pruned RMSD in their tuple of return values, and the latter did a similar thing, though it returns a list of such (now larger) tuples. —Eric Eric Pettersen UCSF Computer Graphics Lab
