**What it does**

Use this tool to create a list of terminal branches from one or more trees that exceed a length cut-off.  

This tool calculates the statistics for the branch-length distribution in each newick tree.  A terminal branch whose length falls past a specified number of standard deviations is reported in 
the output.
The list output from this tool may be used to filter/prune the original PHYTAB sequence file using the tool "Prune phytab using list".

**Example**

Input File (2 tab-delimited columns)::

  GeneA   (((Felis_catus:0.234,Canis_familiaris:0.345):0.567,Equus_monoclonius:3.98):0.564,Mus_musculus:0.456):0.0;
  GeneB   (((Felis_catus:4.123,Canis_familiaris:0.035):0.234,Equus_monoclonius:1.12):0.345,Mus_musculus:0.234):0.0;

Currently, taxon names must only include only alphanumeric characters in two fields delimted by one underscore, for example: 

  Genus_species
  GENUSspecies_sample2010

If 3 standard deviations are selected as the cut-off, then the output from the example above will yield::

  Equus_monoclonius  geneA
  Felis_catus  geneB

Only terminal branches will be identified.  (To remove entire clades subtended by long internal branches, see the tool "phytab_LB_pruner".)
