Dear Bruce and Freesufers,

I tried to run the command and then to load it as an overlay - however I get nothing on the surface of the fsaverage brain. The program is telling me that it is including x-number of voxels into the mask but when I check I see nothing on the surface. What is going wrong here?

Further the approach you proposed doing fMRI on the surface sounds interesting – but I have never used this approach. Could you give me a hint on the steps I need to take in order to do this?

Thanks in advance!

Eric

yes, but do you want to do the fMRI analysis on the surface or in the
volume? There are lots of advantages to doing it on the surface. If your
sig.cluster.mgh was a surface overlay then the threholded.mgh might be
exactly what you want. Load it on an inflated surface and take a look

cheers
Bruce
