Dear all,

I'm trying to place a fragment in certain position. I did this (on
Python IDLE):

from BuildStructure import placeFragment

placeFragment( fragment, resName, model = 'scratch', position=None)


Where fragment = benzene and resName = RING6 but I am not sure about
that .
Could you give me an example of placeFragment code?

Hi Elisabeth,
This will place a benzene ring at the center of the view in a new residue named "BZN" in a new model named "scatch":

from BuildStructure import placeFragment
from BuildStructure.Fragment import RING6, fragDict

placeFragment(fragDict[RING6]["benzene"], "BZN")

Let me know if you have more questions.  Though the placeFragment function does have some documentation, the Fragment.py file doesn't.  Sorry about that.

P.S.  I cc'ed the chimera-dev mailing list on this since that list deals more with programming questions.
