Make sure you can write to the current directory for data files and that you always run from the same directory. The first time you run the script, you will be asked to run with the --makedat option in addition to any other options. This will create the data files for the hostnames and options your specify on the command line. You should only do this once. Subsequent runs should be made without the --makedat option.
