NJPLOT is a phylogenetic tree drawing program that handles Newick tree files, that is files describing trees by the nested parentheses method (e.g. PHYLIP-built trees).

Features:
A graphical interface allows to re-root a tree anywhere and to swap
branches.
Bootstrap values are displayed next to internal branches.
Branch lengths can be optionally displayed.
Tree plots can be printed or saved to a PostScript file.

Program unrooted draws trees in an unrooted, circular form.

Program newicktops uses no GUI and converts a Newick file into a postscript document. 
Usage:
newicktops  newick-file-name
or
newicktops -h      (to see program options)
The result goes to file newick-file-name.ps

Program newicktotxt uses no GUI and converts a Newick file into a pure 
text file where the tree is drawn with | and - characters.
Usage:
newicktotxt  newick-file-name
or
newicktotxt -h      (to see program options)
The result goes to file newick-file-name.txt

Program add_root reads a Newick tree file and roots it with the midpoint method,
that is at the point that minimizes the root-to-leaves variance. It does
no change if the input tree is already rooted.
Usage:
add_root newick-file-name
The result goes to stdout.
