Hi, It is quite interesting to know more about dicom2nifti. And I just encountered a strange problem, too. For 3d images, the output from dcm2nii generally includes 3 files: t1*.nii.gz, ot1*.nii.gz, cot1*.nii.gz. ot1* is from reorienting t1* and cot1* just gets some neck-clip. But on one subject of my data, the output has only t1*. I suspect that some information writtern in dicom files of this subject is abnormal, which leads to the change of dcm2nii result. Although I could reorient it by hand, I am still puzzled where it breaks down. Thanks for any suggestion!
