Hello all, I get a directional cosine error when I try to register data
or extract values from them so I tried mri_info and
get this message: mri_info subj1.img matfile: only read
256 bytes of name (810698068 specified) MatlabRead: readHeader returned NULL WARNING: analyzeRead(): matfile subj1.mat exists but
could not read ... may not be matlab4 mat file ... proceeding without it. ----------------------------------------------------------------- INFO: could not find subj1.mat file for direction cosine

cosine? -Thang |
