External Email - Use Caution

Dear Jennifer,

if your nifti1 files are named 'brain_nii.hdr' and 'brain_nii.img', try the following:

mri_convert brain_nii --out_type nii brain2.nii

Best,

Tim

Dear Tim,

Thanks for your response. I'm sure that the command is mri-convert (I was using it few months ago without problems). Btw, we are experiencing problems also with the recon-all command at different computers. I don't know which is the error, any more ideas?

Best, Jennifer

Dear Jennifer,

could it be that you are confusing `mri_convert` and `mris_convert` (note the 's')?

Best,

Tim

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