Hi Jenna

It is pretty straightforward. Just give it a surface as input (see below)

Cheers

External Email - Use Caution

Dear all,

I hope this email finds you well.

I was trying to run mris_euler_number command for QC of the recent Freesurfer segmentation. It seems as though there is no information about the command available in your wiki page. I can see recent literature reviewing the reliability of the command, which indicates the command is still available.

Could you provide me details on different arguments available for the command?

Kind Regards,

Jenna
