Dear all,<br /><br />I am puzzling what the motion criteria is in order to correct one translational shift between two sessions if the motion within each session is in an acceptable range. To my understanding, it seems depending on whether the interpolation can handle it well, right? Say, if I have two sessions that are shifted 10mm in x direction and all motion within session is less than 1mm, may I able to get a reasonable result? Thanks!<br /><br />greetings to you all!<br /><br />Weidong Cai<br /><br />SUNY at Stony Brook
