Tatiana writes: Dear ChimeraX developers, I would like your help to combine two volumes in ChimeraX while keeping the properties of each volume (colour, threshold...). I know it's borderline in ChimeraX, but it seems feasible. I have been playing with morph, vop commands and a lot of information found on the web for several days, but I fail. I'm also asking chapGPT... but I can't manage to combine my two volumes. Could you please help me to combine these two attached volumes. If yes, could you please send me the procedure And one more questions related to this question, How to know the name of the slider after vop morph command to synchronise 2 morph and record a movie. I found a way to do it on the web (via the Tools menu and selecting General Controls to open the General Controls panel. In the General Controls panel you will find various sliders) but I don't have this General Controls menu in ChimeraX. Thank you very much if you have time to help me. Tatiana
