Re: [Freesurfer] Brodmann area thickness, surface area and volume

Hi all, I want to study Brodmann Areas cortical thickness, surface area and volume. I've added the 5.2 BAxxx.threshold.label to my 5.0 fsaverage and run the recon-all BA labels command. Now I run aparcstats2table and get a table with the values but they are the same as before running the B

Ok, that was my guess... I am running against a deadline, any news on automatically computing the correct threshold script? Will I be able to use it in 5.0? Thanks you! Andreia Quoting Bruce Fischl : > yes. Surface area will be the affected much more than thickness (and > volume of cours

yes. Surface area will be the affected much more than thickness (and volume of course scales with area) On Fri, 22 Mar 2013, _andre...@sapo.pt wrote: > Hi Bruce, > > Thank you for the quick response! > > In the meanwhile, does that also apply to cortical thickness and volume? > > Thank you! > >

Hi Andreia the issue is that the BA labels contain every point that has any non-zero probability (no matter how small!) of being in that label. So the total label area is almost certainly always bigger than the actual BA. Anastasia has some scripts for automatically computing the correct thresh
