1    function []=gcmfaces_demo();
2    % GCMFACES_DEMO demonstrate capabilities of the gcmfaces toolbox.
3    %
4    %expected directory structure:
5    %
6    %  gcmfaces     (codes)
7    %  MITprof      (codes)
8    %  nctiles_grid (ECCO v4 grid)
9    %  release1     (ECCO v4 output)
10    %  sample_input (additional demo material)
11    %
12    %the ECCO v4 grid can be obtained as follows:

15    %  mv mit.ecco-group.org/ecco_for_las/version_4/release1/nctiles_grid .
16    %  rm -rf mit.ecco-group.org

20    %  mkdir release1
21    %  wget --recursive ftp://mit.ecco-group.org/ecco_for_las/version_4/release1/nctiles_climatology
22    %  mv mit.ecco-group.org/ecco_for_las/version_4/release1/nctiles_climatology release1/.
