I don’t think you pass the arguments correctly to mri_info. You need to specify an input image – ‘mri_info input.mgz --voxel 0 0 0’.

This should be done after you have sourced Freesurfer environment correctly. Here are the instructions to setup your environment on Mac MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/SetupConfiguration_Mac

Also, which version of Freesurfer you are using?

Ok I tried again and when I inserted the mri_info... the output was "mri_info: could not parse extension from 0"

Can you try ‘mri_info <input.mgz> --voxel 0 0 0’? Just wanted to make sure the license file is read properly.

Can you confirm where your license file is?

To whom it may concern,

I am using freesurfer package on a MacBook Pro (macOS Sonoma, Version 14.1), but freeview shuts down immediately when I try to open any file. The license is in the correct place.

Thank you for your help,

Best regards.
