If, on the keyword line, the word 'SETUP' is specified, then a line of keywords will be read from a file with the name SETUP. The file SETUP must exist, and must contain one non-comment line. Keywords in SETUP are put after all keywords in the data set.
Keywords in the data-set will take precedence over similar keywords in the SETUP file. For example, if "CHARGE=0" is present in the SETUP file, and the data-set contains "CHARGE=2", then "CHARGE=0" will be ignored.
Any keyword in the data-set that is preceded by a minus sign, e.g., -PM6, will remove that keyword from the SETUP file before the job starts.
Any keyword in SETUP that is preceded by a minus sign, e.g., -PM6, will remove that keyword from the data-set file before the job starts.
SETUP is particularly useful when running a large number of jobs that all use the same or similar keywords. Thus if a set of calculations involving PM6 are to be run, then the SETUP file could contain the keyword PM6. The run would then produce a set of archive files, all with the keyword PM6 present. If, later on, the set of archive files files needed to be run using PM7, then the SETUP file could contain " -PM6 PM7"
The location of the SETUP file and its name can be changed by use of SETUP=<name> or SETUP=<file location and name>, e.g., SETUP=protein.txt, SETUP=C:/Users/My_setup.txt, or SETUP="C:/my files/My setup.txt"
For proteins, a useful set of keywords to have in the SETUP file is: MOZYME EPS=78.4 PL GNORM=10 T=4D
