I'm having a devil of a time getting model_vs_data to run in a timely fashion. Running the latest stable Linux build on Ubuntu 14.04 takes on the order of 3 minutes per structure. That wouldn't be so bad if I weren't trying to run it on every entry in the PDB. Is it just a limitation of Python? SFCheck, which I think is written mostly in FORTRAN, runs in a few seconds. Any help anyone could offer would be appreciated. Thanks. :)
