Atom index out of range

[Satyan Sharma <>]

Hi Modeller users,
I am trying to model a 2 domain protein. I give a pdb file with 2 chains
(toatal of 1828 atoms)along with the alignment. During the run I get an
error - Atom index is
out of range.
nselat__596E> Atom index is out of range (iatm,natm):     1829     1828
Any idea what could be wrong

Cheers,
Satyan
