Regarding whether 3dfim+ would give you what you want
and give you basically the same result as 3dDeconvolve,
the answer is "probably", but one point is that we do
not want to support 3dfim+ any more. To say "yes" with
any confidence would require investigation that we no
longer want to do (we see no gain in using that program).
It is not clear what you are doing in terms of time
points, but I have trouble imagining you are doing
anything that 3dDeconvolve could not handle (given
that 3dfim+ does).
Exactly how are you restricting the TRs? Please
provide commands.
