[SOLVED] Cannot generate NCL plot for SST difference in benchmark

[alainF]

Hello,
I am following the tutorial for MPAS. MPAS Tutorial — Practice Session Guide
Now, all is OK until I try to visualize the SST difference with the command
"ncl plot_delta_sst.ncl"
There is an error message that you can find in the attached error.msg read from the terminal window.

Why can't I plot this SST file ?

I have sent to nextCloud, the static file x1.10242.static.nc.txt.

Thanks a lot for your help.

Now, the visualization of the mesh with "ncl mesh_resolution.ncl" does not work for the same reason as above.
This is quite more problematic since I cannot locate the variable mesh grid on a specific region of the globe.

Thank you for any help !

I have found the point !
I have installed NCL package from a pre-built in the Ubuntu official repo. But it seems that some features are not compiled with the package, such as the calculations with the triangular mesh, and maybe also other things.
So, DO NOT use directly sudo apt in order to install NCL package.
You have first to install anaconda3 (at least on 31st December 2022). If you follow the instructions here : Installing NCL with "conda"
then you will surely be successful.
