Hi everyone:

        I met problem about the recon-all process. I got some brain regions showing group-differences of activation in task. Now, i want to compare the difference of cortical thickness on these brain regions. I prefer to limit the compution of cortical thickness on my regions of interest rather than the whole brain to reduce compution time. But i do not know how the recon-all works it out. I need your suggestions.

       In addition, assume that i have finished recon-all process on the whole brain, how can i obtain the cortical thickness of my regions of interest?

 

All the best!
