Hi Rosa, let me see if I have this straight. For a single subject (in a single session?) you have multiple runs. Each run only covers a part of the brain (do the different runs overlap?). In the end, you want to have a full brain analysis by combining the different parts. Is that right?

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:
- 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]
- 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?
- 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
