[Chimera-users] automated rebuilding of side chains?

Dock Prep now rebuilds truncated sidechains using data from rotamer
libraries (Dunbrack or Richardson):
It automatically locates the truncated sidechains, retrieves rotamer
information, and chooses the best rotamer based on clashes, H-bonds,
and (by default) backbone conformation. This may take a while... it
sounds like your system is pretty large. It will not add in missing
backbone segments or entire residues, however, only sidechains.
Dock Prep was changed after the last production release (Nov 2007),
so I recommend getting a daily build:
