Sometimes I need to redefine which project the suite will use for a) compute b) scratch.
For a) my solution to date has been to change my default $PROJECT definition in ~/.config/gadi-login.conf, re-login and run.
Then for b) (with thanks to Dale Roberts post here) I have included the following at the top of my rose-suite.conf
root-dir=*=/scratch/$PROJECT/$USER
Where $PROJECT can be updated as required, or left as default.
Perhaps there are cleaner ways to do this through the GUI?
