PUZZLE is a maximum likelihood program for analysis of
molecular sequence data.
After 15 months of stable sources the first bug-fix update
PUZZLE 4.0.1 is now available. No new features have
been added in comparison to version 4.0 but a number of
smaller (and also one severe) problems have been resolved.
Generally, an update seems to be absolutely necessary if
you are using PUZZLE in conjunction with the mtREV-24 matrix.
What=B4s new in PUZZLE 4.0.1:=20
- correction of mtREV matrix:
wrong likelihood values for this model
- fix of the "intree bug":
prevents PUZZLE 4.0 from reading some input trees
- stringent runtime-compatibility check removed:
prevents PUZZLE 4.0 from running on alpha
- more accurate gamma distribution:
16 instead of 8 categories, better alpha > 1.0
- update of documentation:
mainly address changes
- more Unix-like file layout, and
- change of licence to GPL
PUZZLE 4.0.1 is available (or will soon be available) from:
PUZZLE is written in ANSI C. It will run on most computers
if compiled by an appropriate C compiler (e.g., gcc).
