Hi Yasemin - If you upload all the tracula output files for me here, I'll take a look: https://gate.nmr.mgh.harvard.edu/filedrop2/
Please include all the output directories for this one subject in one zip file. Thanks!

Hi,
I'm running Tracula on a longitudinal dataset and it's failing at the preproc stage for one subject with the following message:
INFO: Distances between consecutive points in test subject's space are 16 13 12 14 WARN: Could not find satisfactory control point fit - try 4967 Finding center streamline INFO: Step is 3 voxels WARN: Turning off deviation check for center streamline INFO: Step is 3 voxels WARN: Turning off FA check for center streamline INFO: Step is 3 voxels WARN: Turning off overlap check for center streamline INFO: Step is 3 voxels WARN: All checks already off.

It looks like the problem is with one specific pathway. I checked the brainmask and the inter and intra-subject registrations and they all look fine to me, so I'm not sure what else to check. The trac-all.log file is quite large, I attempted to attach it in this email several times, but it always gets rejected, so I'm not attaching it for now. I would greatly appreciate any advice!
Best, Yasemin
