## Differences with existing tools

There exist tools in Fortran that ship with NEMO that are used to create domain files,
input fields, etc. They are however more used to produce configurations with the
necessary input files, than to analyse the outputs. So there is only one overlap with
xnemogcm, which is recombining the mesh_mask / domaincfg files,
when they have been outputted by different processors.

NEMO output files are outputted as netcdf so they can directly be opened by xarray.
However, what is missing is all grid information in the shape needed by
xgcm (COMODO convention). To solve this problem, another python package
exists: xorca. However, xorca is not developed any more is less flexible than xnemogcm.
