Hi, all. I've spent a few hours wading through documentation and
google searches, but it's possible I've overlooked something obvious.
Apologies in advance, if so...
I've got 15ish subjects from an experiment that I've previously
analyzed with other analysis packages, and I'd like to reanalyze them
with FSL to see if my results are cleaner/different.
Short version of the experiment -- it's an event-related
heavily-modified flanker task. Each subject has three runs per
session. These runs were counterbalanced across subjects. (Subject1's
first run was Subject2's second run, et cetera.)
I've generated a 3-column parameter file for each EV in every
subject's runs, but I don't know how to use those parameter files to
create a FEAT setup file (design.fsf) from the command line. As far as
I can tell, at this point I need to run 45 first-level analyses by
hand. Then, if I want to run the model including temporal derivatives,
I'll need to run another 45 first-level analyses by hand. And if I
want to include the reaction time as a duration instead of modelling
the event as impulses, then it's another 45, and so on...
Is this right? I was hoping there'd be some way of creating a
design.fsf file with command line arguments. Maybe something like:
create_setup_file -volumes run1.nii -addev congruent.txt -addev
incongruent.txt -use_tds ...
Then I could generate those commands from a batch script, and I'd be good to go.
Am I overlooking something? How do other people do this?
Thanks!
Todd
