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( https://secure-web.cisco.com/1AJdw_iZ93Ctl2bXUM-tS9sQoJ_9a6-0RHBNEGqz7c8Pz8G...) 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: Read mesh collection: /home/sgbc/freesurfer/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2/atlas_level2.txt.gz Transforming points Transforming points Read mesh collection: /home/sgbc/freesurfer/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2/atlas_level2.txt.gz Read mesh collection: /home/sgbc/freesurfer/average/samseg/20Subjects_smoothing2_down2_smoothingForAffine2/atlas_level2.txt.gz Killed
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.
