Convert brik/head to nifti WITHOUT installing AFNI

Hi, I have a single ROI .brik/head file that I need to convert to the nii format to use for analyses in SPM. Is it possible to convert a brik/head files to the nifti format without installing AFNI?
Thanks and best,

Installing AFNI would be the most supported way of doing things. But if you’re really trying to avoid it, here’s a couple of options:

  1. AFNIpy[/url] and [url=]Nibable could likely do the work
    2 Freesurfer’s mri_convert looks like it could do the trick.
