-    omission saves disk space and download time. In case you want to run the sub-experiments,
-    you will need to obtain additional inputs. Contact us about this if applies.

  B) in case you want to change stuff on your end, or for troubleshooting
  -----------------------------------------------------------------------
-) to run the core2, ecmwf, and ecco_v4 subexperiments you will need
-    extra stuff in global_oce_input_fields. Contact us if need be.
 ) In linking the experiments to one another we rely on 'build/genmake_local' and
  'input*/prepare_run' which may be worth a special mention, at least to new MITgcm users.

 B) in case you want to change stuff on y
+Line 57 
 B) in case you want to change stuff on y
         e.g. global_oce_cs32 will get shared files from global_oce_llc90. If you move
         the directories appart, you will need to edit the paths in input*/prepare_run
 .4) the logic we followed in linking exps to one another :
-            - forward subexperiments : get local namelists then run input/prepare_run
+            - forward subexperiments : get input.xxx/namelists then run input/prepare_run
-            - adjoint subexperiments : get input_ad.x/namelists then run corresponding forward
+            - adjoint subexperiments : get input_ad.xxx/namelists then run corresponding forward
-            subexperiment input.x/prepare_run (that itself ultimately runs input/prepare_run)
+            subexperiment input.xxx/prepare_run (that itself ultimately runs input/prepare_run)
 ) In a couple .h files (that you find in the build directory after compiling)
     small size parameters are used as a default (to save memory of course)
     and they can become limiting in certain cases :
     - you may want to integrate the model beyond a few time steps. You will need to
-      edit ecco_cost.h, increase nchklev_1, nchklev_2, nchklev_3 and recompile.
+      increase nchklev_1/_2/_3 in tamc.h (e.g. use the values in tamc.h_itXX) and recompile.
     - you may want to use pkg/profiles (i.e. process insitu data via data.profiles).
-      You will need to edit profiles.h to increase NOBSGLOB, and recompile.
+      You will need to increase NOBSGLOB in profiles.h (e.g. use profiles.h_itXX), and recompile.
 ) To run the adjoint subexperiments you need the taf/tamc software/license.
