nope, I would start with the aseg and only check other things if the ventricles aren't accurate On Mon, 18 Jul 2016, Tamara Tavares wrote:

Thank you again Bruce. Since I am primarily interested in ventricular volume, do you think it is necessary to check the the brainmask.mgz for bright or dark spots indicating an intensity normalization error? As well, what about a skull strip error such as removal of brain tissue? I have noticed that sometimes skull strip removes parts of the occipital lobe and I was going to adjust the watershed parameters and re-run recon-all. Do you think this is necessary or would affect the ventricular volume results?

Thank you in advance for your help, Tamara
