Hello!
I’ve successfully built [mpas-bundle](https://github.com/JCSDA/mpas-bundle) and am attempting to go through [this UCAR tutorial](https://www2.mmm.ucar.edu/projects/mpas-jedi/tutorial//202410HOWARD/).
I’ve gotten to part 3.1 Generating BUMP localization files and I’m getting this error when running `mpasjedi_error_covariance_toolbox.x`:
```plaintext
Info : -------------------------------------------------------------------
Info : --- Write NICAS parameters

!!! NetCDF error in netcdf_create_file on task #000002: NetCDF: Parallel operation on file opened for non-parallel access
!!! Hint: file ./bumploc_1200km6km_nicas.nc
```
I’m using the precompiled binaries available in Ubuntu 22.04 for all the NetCDF related libraries (NetCDF-C, NetCDF-Fortran, etc…).
Any ideas what could be causing this?
Thanks!

I ended up figuring this out, I needed to compile NetCDF with parallel support. I was using the default one provided by the distro and it looks like that one was not compiled with parallel support.
