SplitsTree 3.1 RELEASE NOTES This describes changes to SplitsTree since version 2.4. Version 3.1: * I've added a new menu: Fit. Use it to envoke code written by Dave Bryant for recomputing edge lengths: namely using a least square fit, or Fitch-Margoliash using power-1 or power-2. Also, I've added a simple thing that I implemented myself: This computes the average support of all quartets around each of the given splits. (You will notice that Dave's code is really fast and mine is really slow, but Dave is Dave...). This stuff is potentially useful because straight split decompositionr tends to under estimate the support of internal edges. Version 3.0beta: * Version 3.0 never really worked for most people (and it expired at the end of 1998, even if the documentation falsly indicated that it will run longer). * The program no longer requires file splitstree.rsc to run. (If, however, a file named splits.rsc exists, it will be used to set up the menus). Version 3.0 (should have been named 3.0alpha): * Compiled a very first Windows version based on TCL-TK Version 2.4: * The Unix version of SplitsTree now offers command line editing and a history mechanism. (This is based on the GNU readline package, as used by gnuplot.) * The 0README file contains some documentation. Several old bugs have been superseded by new ones.
