I guess my real question is what exactly is in a "cope" file.
First, do they have one volume per regressor or more, and in the latter
case, what are the extra volumes? Second, what do the values in each
volume represent (beta values, t-stats, something else)? Once I know
that, I can figure out whether I can create a cope file from the data
I'm working with.

Okay, then am I correct in thinking that flame does not need as
input any special files (e.g. ".mat" files) created by the first level
analysis?
