Dear Freesurfers,

I have 2 identical DTI sequences for each patient (adquired within the same session), but would like to work with the average DTI sequence in all my subsequent analysis. How to obtain the average of both DTI sequences with Freesurfer, and convert the resulting file into .nii? Does the resulting nii file change the brain hemispheries?

Thanks in advance.

Best regards, Jose
