Hi Jean-Michel
In answer to your questions
1. the previous version of gchem_forcing_sep.F was "1.32 2013/07/04", it
is now at 1.37.
2. no, I don't think so!
3. yes I did clean the directory, I have a script which basically does
the same things as make Clean
4. I used the instructions on that same website using "cvs update -d -P"
in the root ~/MITgcm directory which is from the section of the website
that you recommend. This took approximately 20 minutes or so to update the
whole directory tree. The ptracers_advection.F file is still present in
~/MITgcm/pkg/ptracers
I hope this is helpful information!
Many thanks
Jonny
