Hi Stefano - Have you checked that your gradient table is correct by looking at the output of the tensor fit?

Hi list and Anastasia, if you remember the last week I had same problems with tracula output: the final tract are lacking or incomplete for same subjects. Some of these are less wrong (only forceps major), other have more evident error (you can see this in picture that I have attacked). To resolve this issue I have: 1-checked the correct overlap of dwi and dwi_mask 2-rerun data with new version 5.2 3-rerun new registration using bbregister (fsl/spm option): for example, in the subject of the picture attacked, the .mincost file now contains as first value 0.87 (previous it was 1.1) Please, give me an advise Thanks Stefano ----Messaggio originale---- Da: std...@virgilio.it Data: 12-mar-2013 17.47 A: <ayend...@nmr.mgh.harvard.edu> Cc: <freesurfer@nmr.mgh.harvard.edu> Ogg: [Freesurfer] R: Re: R: Re: Question on tracula and dwi-T1 overlap I got it from mri directory but I'm understanding that this directory isn't ok.I'm attacking the image from dlabel/diff/aparc+aseg.bbr.nii Stefano ----Messaggio originale---- Da: ayend...@nmr.mgh.harvard.edu Data: 12-mar-2013 17.19 A: <std...@virgilio.it> Cc: <freesurfer@nmr.mgh.harvard.edu> Ogg: Re: [Freesurfer] R: Re: Question on tracula and dwi-T1 overlap Can you please answer my question? I can't really tell if the issue is due poor dwi-aseg overlap unless you tell me where you got that aseg volume from. On Tue, 12 Mar 2013, std...@virgilio.it wrote: > Thank you Anastasia.
