Betreff: Re: [Freesurfer] Spearman correlation in FreeSurfer
We don't have a spearman analysis in FS. You can load the data into
matlab and do it, something like
ymri = MRIread('yourdata.mgh');
y = fast_vol2mat(ymri);
% y is now a matrix that is nsubjects by nvertices
% Do spearman analysis on each vertex
sp = yourspearman(y,X); % sp should be a 1xnvertices matrix
spmri = ymri;
spmri.vol = fast_mat2vol(sp,spmri.volsize);
MRIwrite(spmri,'spearman.mgz');
