::!/bin/sh :: An example of a protein with 6 chains in the asymmetric unit. The 6 chains :: are arranged into 3 dimers composed of chains A and B, C and F, and D and E. :: The input PDB file contains the SD atoms of Met residues only, to mimic a :: search using Se heavy atoms. :: This example will run fine with the default program parameters. The program :: finds 3 2-folds relating A to B (Polar 30.03761 -57.17715 179.9996), :: C to E (Polar 70.44804 151.8384 179.9996), and D to F (Polar 45.24121 :: 70.64690 179.9996). These are marked as "Loop 2". There are also several :: cases of "Loop 0" where the operator only acts one way, i.e. improper NCS. professs xyzin %DATA%/1fse_sd_only.pdb < %SCRIPTWIN%\end.dat
