Unfortunately, I wrote this software package back in my PhD days before I was aware of the appropriate procedures for package-level documentation. So although the source code is well documented, there isn't any higher level documentation.
The package is written in Python.
Version 0.1 should work with recent versions of Python 2 (such as 2.7 and probably 2.6).
Version 0.2 has been ported to Python 3 by Zachary Sailer.
The program uses a few C extensions, and so compilation requires the gcc compiler. To install the package from source:
python setup.py build sudo python setup.py install
This package calculates exact thermodynamic stabilities within the model by summing over the entire ensemble of conformations to compute the partition function. When run, it first creates a database that stores all of these conformations, which can take a substantial amount of time. It will run quickly for short proteins <20 residues, but get increasingly slow and memory-intensive after that.
