Sam is a fast FFT-based protein docking program that has been specifically designed to assemble perfectly symmetrical protein complexes with arbitrary point group symmetry.

 

About Sam

Sam is a fast FFT-based protein docking program that has been specifically designed to assemble perfectly symmetrical protein complexes with arbitrary point group symmetry.

Sam was developed by Dave Ritchie and Sergei Grudinin. The project was funded in part by the ANR (Project PEPSI), grant reference ANR-11-MONU-0006.

Download Sam 2.0.4

Sam was developed for use on Linux workstations. It is not available for Windows or Mac systems.

For Academic and Governmental users, a runtime version of Sam may be downloaded free of charge. Corporate users may also download the software for evaluation, although prior agreement with the author is required if the program is to be used for profit.
