External Email - Use Caution
Dear Freesurfer experts,
I am trying to run TRACULA as a complementary analysis on a patients and healthy controls sample. I have read in the tutorial that it is assumed that FreeSurfer has already been run on all the subjects' T1-weighted data because TRACULA will use the aparc+aseg.mgz from each subject's FreeSurfer reconstruction. However, T1s of my subjects are not available for this study and I only have the diffusion images.
I have run the three steps of the trac-all separately (using the default freesurfer files: aseg+aparc.mgz...) and all the processes have ended without errors.
Is this correct? Is it possible to use the default freesurfer files instead of each subject's recon-all files in order to run trac-all?
Thank you very much in advance,
Ainara
