I tried that and I got an error in the Mask function that excludes the inter-hemispheric cut in matlab.
It doesn’t like the lh/rh.pial surfaces of the fsaverage. This is the code: 0001 function mask = SurfStatMaskCut( surf ); 0002 0003 %Mask that excludes the inter-hemisphere cut. 0004 % 0005 % Usage: mask = SurfStatMaskCut( surf ); 0006 % 0007 % surf.coord = 3 x v matrix of surface coordinates, v=#vertices. 0008 % 0009 % mask = 1 x v vector, 1=inside, 0=outside, v=#vertices. 0010 % 0011 % It looks in -50<y<50 and -20<z<40, and mask vertices where |x|>thresh, 0012 % where thresh = 1.5 x arg max of a histogram of |x|. 0013 0014 f=(abs(surf.coord(2,:))<50 ... 0015 & abs(surf.coord(3,:)-10)<30 ... 0016 & abs(surf.coord(1,:))<3); 0017 b=(0:0.02:3); 0018 h=hist(abs(surf.coord(1,f)),b); 0019 t=b(find(h==max(h)))*1.5; 0020 mask=~(abs(surf.coord(1,:))<t & f); %%% <---This is where the error occurs %%% 0021 0022 return 0023 end On 1/9/18, 6:41 PM, "freesurfer-boun...@nmr.mgh.harvard.edu on behalf of Douglas N Greve" <freesurfer-boun...@nmr.mgh.harvard.edu on behalf of gr...@nmr.mgh.harvard.edu> wrote: You can map it onto fsaverage, which is made only from 40 subjects, so there is a little more folding On 01/09/2018 06:27 PM, Duran, Tugce wrote: > Total N is 159.
