Hi Leonardo, The morphing is only on the atomic positions, so it doesn't matter whether or not you calculated or colored molecular surfaces on the starting structures. Instead you would first create the morph trajectory model (of atomic positions) and then replay it, showing and coloring the surface for each frame of the morph trajectory during playback. This process involves using the "coordset" command to play the trajectory and the "perframe" command to apply other commands to each frame. This currently works fine for "mlp" as described in the last two commands in this previous chimerax-users post: <https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu/...> However, my testing of the same approach for "coulombic" revealed some bugs that prevent it from working correctly. A fix has been applied to the code but is not yet available in the daily build. I will get back to you next week after I can test the future daily build to make sure it works.

Dear ChimeraX community, I hope you are well. I have a set of models for which I want to show the exposure of specific regions as protein changes conformation through morphing. I can do a morphing between atoms or ribbons, and that looks ok, but the presentation would benefit from a morphing between surface representation coloured by electrostatic potential of each state. I scavenged the youtube tutorials and chimeraX documentation but could not find a way to do it. Would anyone know how to produce this? All models have identical sequence and I calculated the surface for all of them. Thank you for your time, Kind wishes, Leonardo
