Hi - It's hard to tell from the screenshot. Can you please send your entire log file from scripts/trac-all.log? The error seems to be related to the gradient table, so if you can also send that and the b-value table, that'd be great.

Best,

a.y

Hi Professor，

Thank you for publishing Freesurfer software. Now I am studying DTI using Freesurfer. And I am interested in the technology of TRACULA. But when I run it, I encountered an error about valid frame numbers, as shown in the picture. And there is my dmrirc file. Do you know which part is wrong? Have you met this error? My DTI data has 63 directions. I don't know how to correct it. I really appreciate your help. I am looking forward your reply. Thank you very much.
