Hi Emad - I believe that it's not finding your freesurfer recons. They should be under the $SUBJECTS_DIR and have the same names for time points and longitudinal template as what is under your tracula output directory (if the latter is different from SUBJECTS_DIR).

Best, a.y

Hi Anastasia,

I’ve attached the log files. The cases are:

1. Case #2; time points: 2a, 2b; base template: 2tem
2. Case #3; time points: 3a, 3b; base template: 3tem

Thank you again for your help, Emad

Hi Emad - The error happens at the very beginning, so I'm wondering if something went wrong in the previous steps, before -path. Can you please send me the entire trac-all.log of one of your subjects? Thank you!

Hi Anastasia,

I hope you’re enjoying your evening!

I’m doing longitudinal TRACULA analysis on two subjects, each having two time points. I have already taken the steps of longitudinal recon-all and trac-all -prep & -bedp.

Now I’m trying to do trac-all -path, but it gives me an error that I cannot recognize. I would greatly appreciate your help. I’ve attached the log files and the config file.

Thank you so much, Emad
