---- downloading matlab toolboxes ----

1) create a directory called `iap-idma' with a subdirectory called `iap-idma/matlab'

2) open a web browser and download the following two files:
     http://mit.ecco-group.org/opendap/ecco_for_las/version_4/checkpoints/c65r_gcmfaces.tar.gz
     http://mit.ecco-group.org/opendap/ecco_for_las/version_4/checkpoints/c65r_MITprof.tar.gz

3) move these two files to the idma directory and uncompress them.

3) the iap-idma directory should now contain two subdirectories
   named `c65r_gcmfaces' and `c65r_MITprof'. Rename them simply 
   as `gcmfaces' and `MITprof'

notes : 
- disk space requirement ~ 800M (plus session specific items that will be added later)
- 2011 or later matlab version is needed (for native netcdf implementation)
- for session 1 you only need MITprof but gcmfaces will come 
  handy later so your might as well download both right away

---- for session #1 ----

1) see 'downloading matlab toolboxes'

2) download idma_float_plot.m, idma_box_subset.m, and idma_box_mean.m from 
     http://mitgcm.org/viewvc/MITgcm/MITgcm_contrib/gael/comm/course-idma2016/matlab/

3) move these files to the iap-idma/matlab directory   

4) using you favorite ftp client (e.g. fetch in iOS, secureFX in MS-windows, 
   or wget in LINUX) to download the following directory:
      ftp://mit.ecco-group.org/ecco_for_las/version_4/release1/MITprof_release1
   
5) move MITprof_release1 to the iap-idma directory

6) start matlab, go to the iap-idma directory, and type:
   addpath matlab/
   [p]=idma_float_plot('4900828');
   idma_box_subset;
   idma_box_mean;

notes :
- disk space requirement ~ 6.4G (plus 0.8G from steps 1,2)
- idma_float_plot.m and idma_box_subset.m both add the 
  iap-idma/MITprof/ and its subdirectories to the matlab path
- idma_box_subset is the most time consuming, and may take ~3'
