Hi, there,

I have a case_1.hdr file and case_1.img file, but no the corresponding .mat file which contains the necessary direction cosine info.
So everytime when I try to register another nifti file case_2.nii to it using tkregister2 or mri_vol2vol, it always complains that

"INFO: could not find ../../case_1.mat file for direction cosine info.
INFO: use Analyze 7.5 hdr->hist.orient value: 0, transverse unflipped (default).
INFO: if not valid, please provide the information in ../../case_1.mat file"

Just want to know if there are other methods I can use to register case_1 and case_2? Any kinds  of method!

Thanks a lot!
