Hi Doug & Ohers,
I see that there are nice interfaces between Feat and Freesurfer for rendering Feat output onto the surface. Now for group fMRI stats it would obviously be advantageous to do all the stats directly on the surface, avoiding volume space altogether. Especially clsuter thresholding might be an issue here. Am I correct there?
What approach would you suggest in terms of what software to use for the fMRI analysis. In our lab we have used mainly FSL tools to do volumetric fMRI analysis, and are hence most familiar with these, but are considering to moving to doing all this on the surface. What are people's views on that? Is that an entirely good thing or are there advantages to volume space analysis? What if spatial distortions are present in the BOLD images and haven't been corrected for? Any comments and suggestions on these issues would be greatly appreciated.
Thanks a lot,
Christine
