[chimerax-users] Perframe and distance

Hello! I am trying to measure the distance between two atoms in my trajectory in every 10th frame. My approach was to use the perframe command paired with the distance command. Below was my attempt: perframe "distance /D:15@NH1 /B:42@OD1;distance save dist$1.txt;~distance /D:15@NH1 /B:42@OD1" interval 10 However, it instead simply outputs the distance of the currently displayed frame over and over again. Any help would be appreciated! Ben ......................................... Benjamin Simonson MCIBS PhD Candidate Penn State University
