mrca

Find the most recent common ancestor (MRCA) of a set of tips in a phylogenetic tree

Use

The input tree (-t) must be rooted and in newick format, with internal nodes labelled. Tip names are matched by providing a regular expression to -r:

> mrca -t rooted.newick -r "in|out0"
Node2

The MRCA node's label is written to stdout. If the MRCA is the root of the tree, "root" will be printed if the root node is not named.

Help:

./mrca -h
Usage:
   [flags]

Flags:
  -h, --help           help for this command
  -r, --regex string   regex of tip names to parse
  -t, --tree string    tree file to read (in Newick format)
