Hi Ahmad, Not sure I understand what you actually want, but I’ll try to answer anyway… If you mean you want to see a gradual change in position from pos6 to pos5 then you would need to put a frames number after pos5, for example: crossfade 50; view pos5 50; wait 50 <http://rbvi.ucsf.edu/chimerax/docs/user/commands/view.html#name> (Crossfade does not interpolate the movement, you have to do it with the view command.) <http://rbvi.ucsf.edu/chimerax/docs/user/commands/crossfade.html> Some minor notes on scripts. You do not need “;” at the end of any line; it is only needed to separate commands that are on the same line as each other, as in the example above. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/usageconventions.html#cxc-f...> I hope this helps, Elaine ----- Elaine C.

I want to crossfade pos6 into pos5, the crossfading itself is smooth, but the below script gives me an abrupt transition at the start of the crossfade (at pos6), how can I fix that?!
