[PyMOL] a scaling question

[Fei Xu <fe...@ru...>]

Hi!:
I met a scaling problem.
I created many pdb files along one trajectory of DNA movement. I loaded
each pdb file in pymol to create a picture, that is, one frame of the
trajectory. Pymol shows each molecule in an optimal size automatically
according the general shape of the molecular. The shape of the molecule
along trajectory kept changing so that the size of the molecule also kept
changing. When I connected all the time frames together, I saw the funny
effect that the molecule was jumping back and forth.
How can I put the molecule in the different time frames in exactly the
same size?
Thanks!
