Hi FSLers, I'm looking for a way to run Feat in batch mode without having to go through the viewer. I know that I can create a design.fsf, save it, then run "feat design.fsf". However, what I'd really like to do is use the Feat GUI to define the parameters of the first-level analysis once-and-for-all, then apply it to other data sets without having to invoke the GUI (premised on the assumption that they all have the same design of course). Can feat be invoked something like: feat design.fsf my-new-fvol.img which might tell feat to ignore whatever is listed as the input volume in the design.fsf and use my-new-fvol.img instead. Then I could just define design.fsf once and then set up a script to loop through all my volumes. I know that I can have my script hack into design.fsf, but I'd rather use any functionality that exists now. thanks doug -- Douglas N.
