ARB_NT/Tree/Parsimony/Tree/Add Selected Species + NNI
DESCRIPTION
The 'selected species' (see ´Glossary´) is positioned
within the current tree according to maximum parsimony criteria.
Local optimization of the current tree is performed by swapping
subtrees which are separated by not more than one edge.
NOTES
The current parsimony value (number of base changes needed) is
displayed after the 'Current Par' prompt in the upper part of
the 'ARB_PARSIMONY' window and the 'Message' window (pops up
while calculating).
