Hi Ariel – Have you run freesurfer on the structural images of your subjects? Are those freesurfer recons found in what you have defined as SUBJECTS_DIR in your configuration file?

Best,

Subject: [Freesurfer] TRACULA ERROR!!

Dear fellow researchers,

I am running tracula pre-processing step, and the computer showed an error message:

Location of aparc+aseg's relative to base: dlabel/mni/aparc+aseg.nii.gz

Brain mask for output subject: Segmentation fault (core dumped) 

Linux Brain 4.2.0-27-generic #32~14.04.1-Ubuntu SMP Fri Jan 22 15:32:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

trac-preproc exited with ERRORS at Sun Aug  6 23:37:59 EDT 2017

I am sure that I have the aparc+aseg file in the right directory but it showed that the files are missing.....

I would be really appreciated if anyone could please help!!! Thanks so much!!!

PS: I attached trac-all.log as an attachment. Thanks

Sincerely,

Ariel
