ncview is a visual browser for netCDF format files. Typically you would use ncview to get a quick and easy, push-button look at your netCDF files.
Load the ncview module corresponding to the version you want to use, e.g
module load ncview/2.1.7-nsc1
This will add the ncview application to your search path.
To run ncview interactively, allocate a compute node for interactive use and then run "ncview". E.g
interactive -N1 --exclusive -t 00:30:00 module load ncview/2.1.7-nsc1 ncview ifile.nc
When running the ncview GUI, NSC recommends using ThinLinc to access Tetralith.
