To run ROCS you will need to obtain a license file for ROCS from OpenEye Scientific Software (support@eyesopen.com). The license file will be one of the 2 options:
oe_license.txt and must be placed in the directory
specified by the environment variable $OE_DIR.
$OE_LICENSE.
If you intend on running multi-processor ROCS via PVM, only the master machine needs access to the license file.
