Hi Zsuzsika,
sorry, not a genius, but the two things I would try are one, check the
mask.img that is created during the analysis; sometimes this goes wrong
and then it's "no mask, no voxels". And two, whenever I see spm8/spm8
paths, I get worried about the installation being in order (for example,
the file ID I have on spm_fmri_est.m is 3691). Try re-downloading and
re-updating spm8, overwriting the original files with the newer ones,
and only add spm8 to the matlab path. Not sure this helps, but maybe
worth a shot.
Cheers,
Marko
