Dear "O" gurus,

In the absence of the resources offered by the "O" WWW server (it is currently
unreachable due to hardware trouble I understand), I am turning to you for a
quick bit of advice on a fairly straightforward problem.

I have a model refined to R=0.20 at 1.8A, in which all but 9 of the approx 300
residues have been built.  I see "patchy" density for the remaining residues,
and I would like to build them in in the hopes that the improved phases will
reveal the entire chain.  I would like to build 2 unconnected sections of 
3 residues, but I'm not sure of the best way to accomplish this in "O".  The
model was built with Frodo, and only recently have I discovered the "joy of O".
I have never built in O at all, so any pointers to useful info would be much
appreciated.  As well, quick suggestions as to potential troubles in building
such a "disconnected" model would be helpful.

Thanks in advance,

-Darren Nickerson
