Thank you for the reply. For some reason, when I change the DCM file to nii and look at them, in majority of our subjects, the cerebellum and lower brain stem has been cut off, but in this specific subject, I don't think the CST is truncated or out of field more than any other subjects that the TRACULA steps have been run for without any errors. I have taken a few screenshots of both this subject and another one whom -prep and -bedp have been run for without any errors and uploaded them to google drive. Please find the link here:

Moreover, it is worth mentioning that this specific subject had profound global atrophy with diagnosis of Alzheimer's.

As always, I appreciate your time and help.

Kind regards,

Any chance that part of the left CST is truncated in this one subject? E.g., if 
the top part of the brain was outside the field of view?

Anastasia.

Subject: trac-all -prep -c ERROR

Dear experts,

I am running TRACULA for 90 subjects. Exceptionally, for one of the subjects, I get the following error in -prep step:

((INFO: Distances between consecutive points in test subject's space are 10 13 12 13 13 12

I am attaching the log file as well: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://drive.google.com/file/d/1pgEmkMtk4UoELpGR2bU_Vac-2BDr-eNy/view?usp=sharing

On a quick look, aparc+aseg seems to be properly done. Will you please help me to troubleshoot this if possible?

Thank you,

Ela
