TreeView manual<br />

11/10/04 3:10 PM<br />

Windows<br />

A toplogy-dependent bug related to 2 below meant that sometimes rooting the same unrooted tree topology<br />

with the same outgroup would yield a slightly different rooted tree. (Ross H Crozier, Daiske Honda,<br />

Matthew Rain). This was because an internal branch would sometimes be erroneously deleted when the tree<br />

was rerooted.<br />

The broken link to TreeBase has been fixed (Gregor Hagedorn).<br />

Negative branch lengths are now set to zero, so that the tree does not have "backwards" branches (Paul<br />

Lewis, Tosak Seelanan, Ågot Aakra)<br />

TreeView now handles NONA files with taxon names, providing those names start with a letter and don't<br />

contain extra symbols such as '-'. (Joshua S. Layne, Wilbert Hetterscheid)<br />

The Define Outgroup dialog box has been improved to make it easier to use.<br />

The current settings in the Print Trees dialog box are now saved everytime you use it, so if you have a<br />

layout you like, you don't have to continually reset the number of trees per page, tree style, etc. (Jennifer<br />

Steinbachs)<br />

Toolbar tidied up with some extra buttons added.<br />

A bug restricted to the Windows version would sometimes render the program almost invisible except as an<br />

icon on the Taskbar. This usually resulted if TreeView had not exited properly and had corrupted its settings<br />

in the Windows Registry (Matthew Pocock, among others).<br />

Toolbar now has tooltips.<br />

The often reported problem of TreeView failing to start at all on some Windows machines is due to<br />

TreeView needing a printer driver installed (see the FAQ Why won't TreeView for Windows start? ).<br />

TreeView still needs a driver, but will give an error message altering you to the problem, rather than just<br />

crashing. This problem usually arose if people installed TreeView on a new PC without any printer drivers<br />

installed.<br />

1.5.3 November 25 1998<br />

MacOS<br />

Incompatibility with MacOS 8.5 fixed (picture buttons would not display properly, and print preview in the Print<br />

Trees dialog no longer worked).<br />

1.5 February 23 1998<br />

Both<br />

MacClade/COMPONENT-style tree editor, improved drawing of unrooted trees, copy/ paste tree descriptions to/<br />

from Clipboard, support for MEGA tree format, import list of taxon names, access to TreeBASE via Web browser.<br />

1.4 6 March 1997<br />

Both<br />

Support for bigger trees (500 taxa), printing a tree over more than one page, printing more than one tree per page<br />

(the Print Trees command). Status bar added.<br />
