Using CDO on RCC Resources#

In order to run CDO, start by logging into an HPC login node and running the program with any appropriate options and inputs for your job. Then, simply type the cdo command into the command line. Calls to CDO functions generally follow the pattern:

cdo [COMMAND] -[OPTS] [INFILE] [OUTFILE (if applicable)]

Where [COMMAND] is the cdo operation you wish to perform and -[OPTS] is a list of command line options. CDO commands usually have an input file required in the argument list and may also have an output file required as part of the argument list depending on which command you are running.
