Please note that the environment variable GRASP needs to be set in order for the scripts to work.
The environment variable is set by issuing the command (assuming we are using the gfortran compiler)

source ./make_environment_gfortran

in the installation directory. To run the script type

./sh_copper

Please be aware that this calculation is using rci4 but the screening method is that of the original
GRASP2K screening.
