[Chimera-users] Attribute Calculator by command line?

[Hurt, Darrell (NIH/NIAID) [E]]

Too bad! If someone has a solution, I'd be happy to hear it, but if not, that's OK, too.

Thanks Elaine!

Hi Darrell,
As you found, there isn't a command version of Attribute Calculator, sorry!  Maybe one of the others can suggest a python solution?
Best,
Eliane

Hi Chimera friends,
I'm trying to calculate convexity as demonstrated in the Attributes tutorial:
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/attributes.html
I can do it with the graphical tools without a problem, but when I try to do it via the command line, I run into trouble. I cannot find any documentation on running the Attributes Calculator on the command line. I've tried using "setattr":
setattr a convexity atom.areaSAS/atom.areaSES
This command generates a new atom attribute called "convexity" for every atom, but the value of this attribute for every atom is literally "atom.areaSAS/atom.areaSES" instead of the calculated value.
Is there a way to calculate a new attribute value on the command line within Chimera? Sorry to be so demanding…
Thanks,
Darrell
