[Freesurfer] TRACULA (dmri_motion)

Dear TRACULA experts, I plan to use TRACULA in freesurfer 6 to analyze DTI data. I want to kindly to inquire about the command "dmri_motion". This script,nicely, generates: the SNR, drop out score, # drop out slices and motion parameters.

I highly appreciate if you can guide me to a method, so I can benefit from these numbers in my evaluation to motion in the data. I tried to plot SNR and Fa, or SNR and motion parameters and I found outliers consistent with more motion and less SNR. In this case is it healthy procedure just to remove the outliers?! Are there any ranges of safety for SNR and motion parameters that can be used to include/exclude the images.

Thanks Jon
