COLLAPSE
   N;   set level of tree-collapsing to N 
          0   no collapsing 
          1   if some optimization implies support, keep branch ("rule 3") 
              (this is the default in PAUP*) 
          2   if ancestor and descendant state sets differ, keep branch 
              (this is equivalent to "amb-" of Nona/Pee-Wee) 
          3   collapse branch if some optimization lacks support 
              (this is the default of Nona/Pee-Wee: "rule 1") 
          4   rule 4 of Coddington and Scharff, 1994 
          5   Collapse using SPR 
          6   Collapse using TBR 
   +    collapse trees temporarily for consensus calculations (default) 
   -    don't 
   [    after a search, automatically condense trees 
   ]    don't ( default) 
   Alternatively, the options can be given as strings: none, rule 1, amb, 
   rule 3, rule 4 , spr, tbr, [no]auto, [no]tempcollapse.
