Dear Anastasia, Thank you very much for your answer. In my analysis I have two groups 23 patients and 27 controls. My problem right now is that this change in the results (from the output of trac-all -path -c) gave me different P values between the groups, sometimes the results are significant

Try using mri_aparc2aseg. This is what creates aparc+aseg.mgz from the aparc annot. You can look in the recon-all.log file for the command line (just make sure to change the output file name too so that you don't overwrite aparc+aseg.mgz) doug On 11/24/2014 07:54 AM, wangzhiwei3233 wrote: > H

Hi experts, I wanted to play with Tracula. Strangely, already the first preprocessing step, i.e., conversion to .nii.gz, fails. Apparently, mri_convert (falsely) recognizes my dicom files as MGH dicoms ("This looks like an MGH DTI volume"). Could this be the reason why it fails? Thanks, Janos
