Hi Everyone!

The Beta version of PyRosetta 2.0 is ready for download, here is a brief summary of changes:

Approximately 4x more C++ namespace are bound.
All classes now have proper base classes.
Various usability improvements: better help, better error detection, etc.
Build system has been completely reworked. Supports parallel builds. Beta support for Clang++.
Build bases on Rosetta 3.2 release code (also available soon!).

Binaries for the following platforms are ready for download:
Mac OS X 10.6 (64Bit)
Scientific Linux (64Bit)
Ubuntu Linux distributions (32/64Bit)

For more information and download links please see:

Does this version require Rosetta 3.2, and if so do you have an estimated date when it will be released?

No to the first, and I don't know to the second.

This version of PyRosetta uses Rosetta3.2 libs. But as Steven mentioned it does not require any additional downloads.

I downloaded and tried to use the Mac version, but I get this error:

Python 2.6.5 (r265:79063, Mar 20 2010, 11:39:18)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

ImportError: dlopen(rosetta/utility/, 2): no suitable image found. Did find:

Which is the right Python/GCC configuration that was used to compile PyRosetta?

Thanks, have a nice day

I have copied your post to the build/install subforum.

Hello. Are the constraints related functions implemented in PyRosetta 2.Beta? Can anyone help me about how to introduce a customized constraint? I need to introduce a constraint for the angle between two NON-consecutive bonds.
Thanks in advance for any help, have a nice day!

You may be able to define a series of AtomPairConstraints to have the same effect as the angle constraints - if you know the length of three sides of a triangle, then the angle is known as well. Does that make sense?

I may try that, but my problem is more technical: how do I define in PyRosetta a constraint?
Thanks a lot for any help
