External Email - Use Caution

Dear Freesurfer developers, I have no previous experience in Freesufer and I am trying to go through the tutorial before analyzing my own data. I’m working on the dataset you shared on your website. I work on MacBook Pro Apple M2 Pro 32 GB Sonoma 14.2.1. My Freesurfer version is 8.0.0 beta. I set environmental variable FS_ALLOW_DEEP to 1 as suggested. The dataset was one from the tutorial. The directory name was practice_with_data/dicoms I ran recon-all command:

recon-all -all -i I49 -s Subj001

Freesurfer had worked for a time but eventually it came up with a message:

(0) INVALID_ARGUMENT: input must be 4-dimensional[1,72,72,72,24] [[{{node unet/unet_bn_down_0/FusedBatchNormV3}}]] [[unet/unet_bn_down_0/FusedBatchNormV3/_16]] (1) INVALID_ARGUMENT: input must be 4-dimensional[1,72,72,72,24] [[{{node unet/unet_bn_down_0/FusedBatchNormV3}}]] 0 successful operations. 0 derived errors ignored.

recon-all -s Subj001 exited with ERRORS at Mon Nov 18 21:41:39 CET 2024

label, surf, tmp, touch and trash in Subj001 are empty. I checked the mailing list but I couldn’t find any hint.. Please find attached recon-all.log file.

I would be very grateful for your help!
