1. Where can I download POY from?

You can get the latest release version of POY from:

http://research.amnh.org/scicomp/projects/poy.php

Every official release version has passed all of our test scripts and have no known bugs that could affect the correctness of an analysis. 

The latest development version of the source code with all bug fixes from the development team is available from the Google Code POY4 project website  (http://code.google.com/p/poy4/source). You will need to use subversion and compile your own executables.

2. Can I use the command line of POY 3 in POY 4?

A. No you can't. POY 4 provides much broader flexibility in the kind of analysis that can be performed, and this flexibility could not be achieved if we followed the old command line. The program has also changed fundamentally in the way it interacts with the user, so a more structured system of commands was required. We think that the new structure is much more intuitive and easy to learn too.

3. I found a bug, where can I report it?

If you have found a bug, share your observations in the poy4 group. The POY 4 developers actively monitor the list, and if the bug is confirmed, you can report the bug in the Google Code POY4 project website (http://code.google.com/p/poy4/issues/list)

4. What are the compilation requirements and instructions?

POY requires an ISO 99 C compiler,  OCaml 3.10.0 or later (http://www.ocaml.org), and GNU make. In order to compile in a Unix machine (Linux, Mac OS X, Windows+Cygwin, Solaris), download the source code, and then simply do:

tar -xvzf poy_buildVERSION.tar.gz

cd poy_buildVERSION

./configure

make

make install 

The last command most likely will need to be run as superuser either using sudo or su. You can check the configuration options with

./configure --help
