freesurfers,

we've acquired fMRI data from [slightly different] slice prescriptions, all partial brain slices.  we want to analyze this data all together, but we also want to have the best registration possible [i.e., use bbregister].  what's the best way to do this?  here are the ideas we have:

1. analyze these data on the individual subject's surface with selxavg3-sess.  the one problem is that we don't see how to pass the registration file for each run.  [there are different registrations for distortion-corrected or not]

2. run glms for each run independently and then combine the subject's data together with a FFX analysis.  what's the easiest way to run a FFX analysis with fsfast?

3. upsample these functional data to the subject's anatomy [either volume or surface] and then run the analysis there.  however, this will take a good chunk of memory and compute time.

what's the best thing to do here?  

thanks in advance,
rosa
