Hello! I am trying to measure the distance between two atoms in my trajectory in every 10^th 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
