NJplot is a tree drawing program able to draw any phylogenetic tree expressed in the Newick phylogenetic tree format (e.g., the format used by the PHYLIP package). It was written by M. Gouy (see reference below). NJplot is especially convenient for rooting the un-rooted trees obtained from parsimony, distance or maximum likelihood tree-building methods.
Phylogenetic trees read from Newick formatted files can be displayed, re-rooted, saved, and plotted to PostScript (or PICT for the Macintosh) files. Input trees can be with/without branch lengths, with/without bootstrap values, rooted or un-rooted. Binary as well as multi-branched trees are accepted.

Availability
NJplot is available at http://pbil.univ-lyon1.fr/software/njplot.html for MAC, PC (under Windows95/NT/XP), and several Unix/Linux platforms.
Online help
note: taken from the njplot.help file.
NJplot uses the Vibrant library by J. Kans.
>Menu: File
- Open
- To read a tree file in the Newick format (i.e., the file format used for trees by Clustal, PHYLIP, and other programs).
- Save plot
- To save the tree plot in PostScript format, or in the PICT format for the Macintosh.
- Save tree
- To save the tree in a file with its current rooting.
>Menu: Edit
- Copy
- [Mac and Windows ONLY!] Copies the current tree plot to the Clipboard so that the plot can be pasted to another application.
- Paste
- If the clipboard contains a parenthesized tree, this tree will be plotted.
- Clear
- Clears the current plot so that new tree data can be pasted.
- Find
- To search for a taxon in tree and display it in red. Enter a (partial) name, case is not significant.
- Again
- Redisplay in red names matching the string entered in a previous Find operation.
>Menu: Font
Allows to change the font face and size used to display tree labels.
>Menu: Paper
Allows to set the paper size used by the "Save plot" item of menu "File".
- Pagecount (x)
- sets the number of pages used by "Save plot".
Operations
- Full tree
- Normal tree display of entire tree
- New outgroup
- Allows to re-root the tree. The tree becomes displayed with added # signs. Clicking on any # will set descending taxa as an outgroup to remaining taxa.
- Swap nodes
- Allows to change the display order of taxa. The tree becomes displayed with added # signs. Clicking on any # will swap corresponding taxa.
- Subtree
- Allows to zoom on part of the tree. The tree becomes displayed with added # signs. Clicking on any # will limit display to descending taxa. Select "Show tree" to go back to full tree display.
Display
- Branch lengths
- If the tree contains branch lengths, they will be displayed. For readability, very short lengths are not displayed.
- Bootstrap values
- If the tree contains bootstrap values, they will be displayed.
Subtree up
When a sub-tree is being displayed, allows to add one more node towards the root in the displayed tree part.
