[chimerax-users] Converting Chimera movie script

Hi Vid,
The "clip hither -0.5 120" command in the Chimera script you mentioned moves the near clip plane away in 120 steps of 0.5 Angstroms. To do the same in ChimeraX which does not have the "frames" option for the clip command:
perframe "clip near 0.5" frames 120
This isn't the same if the near clip plane is not yet enabled then the "clip near 0.5" sets the position 0.5 Angstroms behind the center of the displayed models, while if the near clip plane is enabled it moves it 0.5 Angstroms further away. So you could set the starting position 30 Angstroms in front of the center, then move 60 Angstroms back in 0.5 Angstrom steps use:
clip near -30
perframe "clip near 0.5" frames 120
In the future we plane to add the frames option to the clip command.
