Dear Freessurfer experts, i want to convert IMA files to nifti using mri_convert I did the following:
mri_convert 54365413.ima output.nii
I got this error WARNING: bad orientation matrix (determinant = 0) in nifti1 file ... ... continuing.
if I run mri_info on output.nii I see
voxel-to-ras determinant 0
ras to voxel transform: mat = NULL! MatrixFree: NULL mat POINTER!
How can I correctly convert IMA to nifti Thank you for any suggestion John
