External Email - Use Caution        

Hello,

I was trying to convert nifti1 files (.hdr and .img) to nii files using the command:
    > mri_convert -i input.hdr -it nifti1 -ot nii -o output.nii.gz
But this error pop-up:
mri_convert.bin: unknown flag '-i input.hdr'

The same command was working on my unit a few months ago. Does anybody know wha's going on? 

Thank you very much.
Best,
Jennifer
