Thank you, Elaine. That should do it. Distance monitors are indeed useful when looking through a trajectory and I often use the just in this way. However, if you try to output the trajectory as a movie, the numbers are often changing too quickly to be of any use and they become more of a distraction than a useful feature. In this context it would be better to have a look at a distance trace in Plot Distance function in Chimera (is there a plan to bring such features to ChimeraX? - this is one of the few features that make me go back to Chimera, for most other stuff I typically prefer the solutions in ChimeraX). That said your suggestion does exactly what I need. I agree with Tom that having a command to make a pseudobond rather than have to load a file would be a useful feature.

Instead: if you just wanted to draw a bunch of pseudobonds without labels, the way to do it is to create a pseudobond file in a text editor (rows just specify the pairs of atoms you want to draw lines between). E.g. containing lines something like: /A:5@sd /A:1@he1 The file format is described here in more detail, including how to specify the initial color, radius, and number of dashes (which you could also change with other methods after the fact): <https://rbvi.ucsf.edu/chimerax/docs/user/pseudobonds.html#pbfiles> You could just close or delete the distances, or just hide them if you want to have them for later analysis. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi,
Is there an easy way to hide distance labels during the playback of an MD trajectory? Even if I delete or hide the labels in one frame they get generated when next frame is loaded. I tried to include hiding/deleting the labels command in perframe but they flash on before they are removed. Ultimately, I would like to record a movie where only the pseudobonds are shown but not the labels.
Thank you, Józef
