njplot - A phylogenetic tree drawing program for biologists newicktops - draw phylogenetic trees into PostScript file


njplot [options] tree_file

newicktops [options] tree_file

newicktotxt [options] tree_file


This manual page documents briefly the njplot command.

The newicktops command does exactly the same but needs no X11 display. The output is rendered into a PostScript file.

The newicktotxt command does exactly the same as newicktops but the output is rendered into a text file.

This manual page was rewritten for the Debian GNU/Linux distribution because the original program does not have a manual page.

njplot is a tree drawing program able to draw any binary or multi-branched tree expressed in the standard phylogenetic tree format (e.g., the format used by the PHYLIP package). NJplot is especially convenient for rooting the unrooted trees obtained from parsimony, distance or maximum likelihood tree-building methods.

Any rooting of the unrooted tree can be interactively specified using the mouse. NJplot also allows zooming, branch swapping, display of bootstrap scores and saving in the PostScript format. NJplot can therefore be used as a graphical extension of any package of phylogenetic program which employs the standard tree format for storing trees (i.e., with most such packages).


There are only the following options which only work in an x-terminal-emulator, but not in console mode:
Prints out brief help.
Postscript tree file prepared for US Letter paper size.
No window interface, just write the PostScript tree file.
-size n
Font size n used for taxon names.
-pc n
number of pages for PostScript output.
-psize widthxheight
size of PostScript page expressed as WIDTHxHEIGHT.
Show branch lengths if they appear in tree file.
Show bootstrap values if they appear in tree file.
Don't include title in PostScript output.

La 1.1 a donc été recommencée de zéro,
la 1.0 étant trop mal programmée sur de vieux
concepts avec des IF partout, d'où sa lenteur.
