External Email - Use Caution
Dear Anastasia, I have run trac -all -prep in 2 different conditions: a) prerequisite recon-all step was done using freesurfer 7.2.0 b) prerequisite recon-all step was done using freesurfer 6
The first time everything ran smoothly without an error, but when we used aparc+aseg resulted from running recon -all using version 6 of freesurfer, we got the following error for which I also attach the log file to this message: Segmentation fault (core dumped)
My question is that if I'm correct to assume that we can't run trac-all -prep using structural MRI segmentation done by previous versions of freesurfer? The reason I'm asking this is that I have a data from 100 subjects with Alzheimer's Disease. We have been collecting this data over the past 4 years and have done the recon -all step using freesurfer 6 for all of them as we acquired them. If trac-all can't use those segmentation, we have to do this step again for all these 100 subjects.
I appreciate your help and insight. Ela
