55    
56    1) see 'downloading matlab toolboxes'
57       note: make sure to use gcmfaces_20160114.tar.gz or the up to date version of
58             gcmfaces from CVS (rather than c65r_MITprof.tar.gz or earlier versions).
59    2) download the m_map plotting toolbox (use the 'zip archive' link) from
60          https://www.eoas.ubc.ca/~rich/map.html
61       unzip and move it to iap-idma/
62    2) using you favorite ftp client (e.g. fetch in iOS, secureFX in MS-windows,
63       or wget in LINUX) to download the following directory (145M):
64          ftp://mit.ecco-group.org/ecco_for_las/version_4/release1/nctiles_grid
65       and move it to iap-idma/
66    3) using you favorite ftp client (e.g. fetch in iOS, secureFX in MS-windows,
67       or wget in LINUX) to download the following directory (14G):
68          ftp://mit.ecco-group.org/ecco_for_las/version_4/release1/nctiles_climatology
69       and move it to iap-idma/release1/
70    4) start matlab, go to the iap-idma directory, and type:
71          p = genpath([pwd filesep 'gcmfaces/']); addpath(p);
72          p = genpath([pwd filesep 'MITprof/']); addpath(p);
73          p = genpath([pwd filesep 'm_map/']); addpath(p);
74          grid_load;%load ECCO v4 grid into mygrid
75          gcmfaces_global;%declare mygrid as global
76          disp(mygrid);%displays grid variables
77          diags=example_transports;%computes transports (takes ~ 2 minutes)
78          example_transports_disp(diags);%display results
79       then proceed as explained in section 5 of gcmfaces/gcmfaces.pdf
80       to use diags_driver.m and diags_display.m (takes ~ 5 minutes)
