This download contains the C2A package, which must be decompressed, and installed in order to use C2A.
Supported platforms:
Unix
Mac OS X (must have gcc installed, you need to download and install Xcode, which is free)
We do not currently support Windows.
This C2A package will take you as far as adding full atomic detail to a coarse-grain template, but you will still need to minimize the full atomic structure using a physics-based MD engine.
The easiest way to do this is to install the Zephyr program from simtk. Zephyr is a free, user-friendly, graphical user interface to GROMACS.
The harder way is to use GROMACS directly, which we describe in a guide you can find on this downloads page and under the Documents section, in the Supporting material folder. Please note that you need fftw installed in order to use GROMACS. If your platform supports yum, that is the easiest way to install fftw.
