How do I mask a domain?

The .nc file is usually located in the folder: $PROJECT_FOLDER/Grids/$GRID_ID/{$GRID}.nc

The .dat file is usually located in the folder: $PROJECT_FOLDER/. Which .dat file to use is not always clear, so it it good to ask.

where $PROJECT_FOLDER is the main folder for the project, and $GRID_ID is a folder identifying the specific grid, and $GRID is the name of the specific grid. Once you are in the Grids directory, you can always do a: find -name *.nc to try and figure out where the grid is.

Once you are in the working directory, start matlab from mseas:

% matlab &

In matlab, run:

>> pe_mask

Select the .nc file in which you will create the grid, and select the .dat file that defines the coastlines.

Enter the transition isobaths, (usually -10)

Choose default values for the rest of the options, and start masking!
