Hello Elaine,

I am trying to decide if it is better for me to invest time into learning Chimera X or if I should just keep using Houdini FX for most of the animation and rendering. So, there are two things that I have been trying to do but have not been able to find an answer:

1. Is there a way to export some kind of alembic file from Chimera X to import it into Houdini or Maya? I want to export a molecule changing conformation, but I don't see an .abc export option in the documentation.

2. My other question is if there is a way to render a sequence of images from Chimera X to then import them as a png sequence into After Effects. I was able to render an individual frame but I don´t know if I can render a whole sequence.

Thank you,

Daniel.

P.S. Chimera X is amazing

Thank you very much.
And yes, I'm using chimera x.

Hi Daniel,
The "sym" command for building the multimer from monomer has both a "center" option and an "axis" option that you may need to use for helical symmetry.

I'm not sure which program you are using, since the subject line of the message says "Chimera" but you sent it to chimerax-users.

Here is the ChimeraX help for "sym":
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/sym.html>

Here is the Chimera help for "sym" (very similar but not the same as in Chimera):
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/sym.html>

If it is really a Chimera question, (for next time) you could send it to chimera-users@cgl.ucsf.edu instead.

Sym is just for building the multimer. It won't change the coordinates to make them closer to the origin.

I hope this helps,
Elaine
