Hi Tanja, we don't have a turn-key way to do this, but you can do it in
matlab using this function:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/fast_glm_pcc.m,
something like:
cd glmdir
beta = MRIread('beta.mgh');
rvar = MRIread('rvar.mgh');
X = load('Xg.dat');
C = load('contrast/C.dat');
pcc = fast_glm_pcc(fast_vol2ma(beta),X,C,fast_vol2mat(rvar));
mri = beta;
mri.vol = fast_mat2vol(pcc,mri.volsize);
MRIwrite(mri,'contrast/pcc.mgh');
where glmdir is the output directory for mri_glmfit
