Bradley,
The only easy way to do this is to do a command line call to
contrast_mgr on a feat stats directory. However, it can only be called in
such a way that the t-contrasts are calculated at the same time. So
you'll need to provide a design.con file as well:
contrast_mgr -f design.fts statsdir design.con
If that's no good (e.g.because your copes are calulated in some special
way) you'll have to do the f stat calculation yourself in something
like matlab.
Cheers, Mark.
