Ran example code:
$ CABSdock –i 2FVJ:A –p HKLVQLLTTT:CHHHHHHHCC
Using OSX version 10.11.6 and CABSdock build CABS-0.9.13.tar.gz. The link provided to download gfortran on the source page was a dead link, so gfortran (6.1) was downloaded from source https://gcc.gnu.org/wiki/GFortranBinaries for El Capitan (OSX 10.11). Python 2.7 was verified, but installation of nose, tornado, and matplotlib showed conflicts with the root version of python and had to be installed for local user using pip with extension --user or with sudo -H.
Output was generally successful, but the final 10 models (model_*.pdb files) did not show all atom representations. This could be verified opening up the files in a text editor. Only one atom was represented for each amino acid residue.
