Dear FS community

I have an ex-vivo human adult brain MRI, both in T1 MPRAGE and Fiesta. I have recently come across a paper on MRI segmentation using a function called- samseg. From the webpage( MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/ExvivoRecon) I realized that there is a different approach altogether to processing these fixative brains. However, as a first step, when I tried the samseg function, I noticed that the function exited with errors.

The steps where it fails are:

I am using the Ubuntu 22.04 version with RAM 32GB

Freesurver version: freesurfer-linux-ubuntu22_x86_64-7.3.2-20220804-6354275

I would greatly appreciate it if you could help me with MRI segmentation and cortical surface analysis on these brains.

Thanks for your time and consideration.
