Free smallest script

Statistics about the splits not shared between two trees can also be calculated. This is done by considering, for each non-trivial split?splits with more than a leaf element on both sides of the edge?the size of the smallest of the two sets in the split A|B. The maximal, minimal and average size of the smallest set in the splits not shared are calculated and reported. This statistics gives an indication of how "local" the differences are between the two trees?if the smallest set is small, the edge that differs gives a difference in a small sub-tree, if the set is larger, the difference is more global.

The tool can also calculate the set of splits found in any tree (with a count of how often the split is found) and the set of splits shared by all trees in the set. Information about which splits in one tree are also found in the other trees can be reported in an annotated tree.

This tree, output in Newick format, has the same topology as the first tree, but the edges are written as sub-tree f:branch-length, where f is the fraction of the trees that contains the edge, i.e., 1 if the edge is supported by all trees or 0.5 if only half the trees contains the edge.
