Hi Irene, it's not the best way to do it, but it's probably good enough. A surface-based functional analysis would be better. doug

Dear Doug and Freesurfer experts,

I have a question related to the previous post. I have two groups (patients and controls), for which I have both functional and T1 data. I'd like to look at differences in cortical thickness between the groups inside some clusters of functional activation. Would it be wrong to overlay the activations (spmT.img maps) on fsaverage, convert them into labels (through Fill Stats) and use label2label to map them to each subject's surface?

Thanks very much! Irene

After you've gone into MNI space with all of your subjects, then visualizing the results on the surface are of questionable value. If you just want to take a peek, then it's not a big deal, but I would not recommend reporting them in a publication. If your results are in the mni152 space, you can try

tksurfer fsaverage lh inflated -aparc -mni152reg yourfile.img

Hello,

I have second-level results in .img/.hdr format that I have just run through SPM. I was wondering whether there is a way to visualize these results onto a template FreeSurfer surface model in MNI space. Is this possible, or can you only visualize second-levels which have been processed through FreeSurfer?

Thanks,

-Andrew
