Sara,
In answer to your question, hydrogens are assigned to groups by attachment,
not distance.
Do check your version. Could be there was some bug at one point relating to
this, but I don't see it now. Are you saying that with
selectionHalos on
you get that H highlighted both with
select 232
and with
select 227
? I remember at one point we had the problem that Hs were not being added
to groups, but that's been fixed long ago.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
