Hi all FreeSurfer Experts, I'm a young researcher, PhD student of the University of Padua with a degree in Mathematics. I'm trying to use FreeSurfer for analyze a 3D image MRI, DICOM format (I have NIFTI too) to calculate brain volume.

I ran

recon-all -autorecon1 -autorecon2 -subjid <..."file with extension .mgz, after the conversion with mri_convert from a unique file .nii" >

and I obtained the errors that you can see in the attachments.

Any suggestion?

Thank you in advance. Michele.
