David, I am experimenting with some new stuff along these lines which will provide much greater control over what moves and what doesnt. For the time being, try using the protect and deprotect commands to control which atoms are subject to transformation.

Horita Sent: Thursday, May 08, 2003 12:20 PM To: pymol-users@lists.sourceforge.net Subject: [PyMOL] pkfrag Hi, Is there a way to explicitly control which atoms end up in pkfrag1 and pkfrag2? Specifically, I'd like to be able to move/rotate fragments which are made of multiple molecules or are internal loops. Using pkbond or pkatom to break between fragments doesn't give me enough control. Selecting and protecting atoms doesn't seem to help, in this case.
