Hi there, I am using freesurfer for datas of two year olds. - Is there a special command to run freesurfer on children's data? - When I checked the seg.stats for volumes, I got a higher value for BrainSegVolNotVentSurf (value: 845377 mm3), than for the BrainSegVol (value: 839497) in one patient. The recon-all -all finished without error. How is this possible?
Thanks in advance, Kristina
Hi Kristina
do the results look accurate. 2 is pretty close to (or past) the limit of where we generate reliable results.
Not sure about your other question - I don't remember how they are calculated. Someone else should know, although note that we are putting on a class this week so response times will be slower than usual
cheers Bruce

They are not computed in exactly the same way, but the results are still a little surprising. What is the value of BrainSegVolNotVent? That should always be less than BrainSegVol.
