Dear FS experts,
I'd like to know the fsaverage brain (rendered brain) generated after recon-all analysis is same as that of individuals brain size. I mean is rendered brain developed after recon-all = individual brain??
If not,
How much cm/mm away or towards the original brain??
Hi Anupa
sorry, I don't understand the question. Fsaverage is the average of a bunch of subjects (40 or so I think). What do you mean by "size"? It certainly has less surface area than any individual in it, since the averaging smnooths it. We store this in the surface so that we can correct for it e.g. when doing surface-based smoothing Bruce

Dear Sir, I'm attaching the surface (Pial)that we get after recon-all analysis. This is the left brain of a subject. WHat I meant in my previous question is that, does the sulcal and gyral info, that is present in this image is exaclty similar to that of patient's brain. I hope I'm clear with my question.

Still not positive I understand, but I think the answer is yes. The image you showed is a model of your patient's brain, with all the correct physical dimensions
