[chimerax-users] Crossfade rough transition while making a movie

[Elaine Meng]

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

(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.

I hope this helps,
Elaine
