Hi Jason,

The manual state that "contact" command calculates the contacts between all
the atoms of the <mask>. I wanted to know whether the same can be done
between two masks. Like if I want to calculate the contacts made by atoms
in :1-10 only with the atoms belonging to :11-20. If I give :1-20 (as only
one mask can be specified) as mask, the contact command calculates contacts
between an atom of residue 1 with that of residue 2 and so on, which I
don't want.
