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!
