Hi "Someone Else" -
The `rotate` command (http://pymolwiki.org/index.php/Rotate) actually
transforms the atomic coordinates of the object in model space, which I believe
are only stored to 3 decimal places (as in PDB files), so there will probably
be some slight changes in how the surface is rendered between frames. What
should work better for you is the `turn` command
(http://pymolwiki.org/index.php/Turn), which achieves a similar result, but
instead moves the camera, so the atomic coordinates (and therefore the surface)
will remain the same for each frame.
Also, you can generate these kinds of movies directly in PyMOL without having
to write a .pml script for each frame, using e.g. the `mset` command. Check
out http://pymolwiki.org/index.php/MovieSchool, which has a good introduction.
Hope that helps.
Cheers,
Jared

Hi,
I made a movie with rotating protein structure:
https://vid.me/Y4Nb
The structure itself is static, so the surface should also stay the same. But
it clearly changes during the movie. Any round-off errors? Is there any fix
for this problem?
I rendered frames for the movie by generating a set of PML files like:
load 2gb1.pdb
rotate x, angleX
rotate y, angleY
ray 800,600
png frame_i.png
Thanks for your help,
