Sorry, I don't know what you mean by enorm threshold. Can you elaborate?

Dear team,

I am using mc-afni2 to perform motion correction on dynamic PET images 
(ref: petsurfer wiki page). I am planning to use an average of 
un-censored frames as a template to do so. What should the threshold 
be to estimate these set of un-censored frames? For fMRI we usually 
use 0.2 or 0.3 for motion. However, for PET data we have values in the 
enorm file ranges from 0-40.


Thank you,

Sneha
