Dear Freesurfer experts,

I have also noticed something wrong with the tracts I reconctructed. There were no erroors during the processing, but when I visualized all tracts in Freeview according to your command "freeview -tv my-subject/dpath/merged_avg33_mni_bbr.mgz", but the results seem a bit odd to say the least. Please have a look at the attached image.

I have also notice abnormal volumes of these tracts in comparison to your elmo-subjects. For example the volume of left uncinate for your tutorial subject elmo.2012 is 393 and for my subject it is 5459. This discrepancy seems to coincide with with what you can spot in my screen, because it was my first impression that these tracts are extremely large.

I run tracula with default commands as you stated in your tutorial, no major changes were made. If there is anything you could advise me, I will very grateful. Are these results ok or I should udertake some steps? If you perhaps need some additional information I will be pleased to provide you with that as well.

Cheers,

Jacek

Dear Anastasia and Tracula users,

 

I succesfully ran the longitudinal Tracula procedure for one subject. However, when I visualized the tracts, they look a bit weird (not smooth). Even if I played with the threshold on freeview, I couldn't make them look nice as in the wiki page. I checked the registration and it looks accurate, so I am not sure what could be wrong. I am attaching the messy looking tracts for your reference.

 

Could you tell me if I should run again with reinit=1 for these tracts?

 

Thank you very much for your time.

Best regards,
