[Freesurfer] Conversion of an mgh file to nii

Hey there,

I am trying to convert an mgh file I created into an nii volume so I can load it in AFNI. I was trying to use mri_convert, which I have used previously to make nii volumes from my aparc+aseg and it worked great, but this time the resulting file is faulty.

I've noticed a previous thread where someone ran into a similar problem, and it had to do w/ too many vertices existing for NIFTI, and Doug suggested using mri_surf2surf, but it didn't work for that guy or me (at which point I think he was sending you files).

Seems like it should be something common and trivial, but I can't get it too work, any suggestions?

Thank you, Omer Tal UCSD Keck Center for Functional MRI
