4. Using the command line

Run the following command to print help and check that it runs: cis --help

The following should be displayed:

usage: cis [-h] {plot,info,col,aggregate,subset,version} ...

positional arguments:
    plot           Create plots
    info           Get information about a file
    col            Perform collocation
    aggregate      Perform aggregation
    subset         Perform subsetting
    eval           Evaluate a numeric expression
    stats          Perform statistical comparison of two datasets
    version        Display the CIS version number

optional arguments:
  -h, --help   show this help message and exit

There are 8 commands the program can execute:

  • plot which is used to plot the data
  • info which prints information about a given input file
  • col which is used to perform collocation on data
  • aggregate which is used to perform aggregation along coordinates in the data
  • subset which is used to perform subsetting of the data
  • eval which is used to evaluate a numeric expression on data
  • stats which is used to perform a statistical comparison of two datasets
  • version which is used to display the version number of CIS

If an error occurs while running any of these commands, you may wish to check the log file ‘cis.log’; the default location for this is the current user’s home directory.

4.1. LSF Batch Job Submission

CIS jobs may be submitted to an LSF type batch submission system (e.g. the JASMIN environment) by using the command cis.lsf instead of cis. In this case the job will be sent to the batch system and any output will be written to the log file.
