Subject: creating a unit wth xleap

hi,

I have two prep files, with two residues that I have created, APN and
GPN.

After I input them with

loadamberprep apn.lib
loadamberprep gpn.lib

I have two units, APN and GPN. How can I make this
a single unit? I have tried addUnit and CreateUnit but unsuccesfully.

I am trying to bond two atoms and the manual says xleap will only
bond them if they belong to the same unit.
When I say
model=loadpdb pdbfile
doesn't this create a single unit named model?

thanks, Marcela
