Hi Anastasia:

I followed the tutorial notes and don't feel anything wrong with the dmriri.tutorial file, but still encounter the same error while running the preprocessing step.

Can you please check the reason?   

Thank you very much.
Best regards
Xin

Hi

I downloaded the FreeSurfer tutorial data  (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Data) and tried to test TRACULAR. 

In the preprocessing step by running $trac-all -prep -c $TUTORIAL_DATA/diffusion_tutorial/dmrirc.tutorial, I got the following error messages. 

ERROR: length of pathway list (lh.cst_AS rh.cst_AS lh.ilf_AS rh.ilf_AS lh.unc_AS rh.unc_AS fmajor_PP fminor_PP lh.atr_PP rh.atr_PP lh.cab_PP rh.cab_PP lh.ccg_PP rh.ccg_PP lh.slfp_PP rh.slfp_PP lh.slft_PP rh.slft_PP) and endpoint label ID list
ERROR: () do not match

There may be something wrong with the demo dmrirc.tutorial configuration file, which is attached to the email. Please help me with how to fix the problem.

Thank you very much.
Best regards
