yea, you can do something like
a = MRIread('aseg.mgz');
rhovol= a;
rhovol.vol = zeros(size(rhovol.vol));
lhip = find(a.vol==17);
rhovol.vol(lhip) = left_hippo_rho;
MRIwrite(rhovol,'rhovol.mgh');On 12/11/2018 11:41 AM, Conchy PF wrote: > > External Email - Use Caution > > Dear Greve, > > I would like to represent the r values (correlations calculated in > Matlab) from specific subcortical regions (hippocampus, for example) > in a subcortical segmentation (aseg.mgz), so I can load the aseg.mgz > and visualise it using Freeview. > > Shall I use MRIRead & MRIWrite to change the values in aseg.mgz?
