Thank you Bruce and Moo Chung I will try with those tools
I have another question:
If I want to use GRFT on smooth thickness spms over the fsaverage subject , should I use the fsaverage white matter total surface area which is 70394.7 mm2 or the group average surface area which is 86444.7 mm2?
In advance thank you
Jorge

Hi Jorge,
You can make your own fsaverage. In the QDEC wiki page you can find a quick howto.
Best regards

It depends on how you measure the FWHM that you are going to plug into GRF. How are you computing it? If you are using our tools, then you would use neither. Rather, you'd use the average surface area for the group. This is stored in the average surface. You can determine it with mris_info
