Where in the output file are you seeing asterisks? Can you post an 
example? Typically this happens with really large models, since PDB is a 
fixed-width format and has only 5 digits for the atom serial number and 
4 for the residue number, so if you have 100,000 or more atoms in your 
system PDB format is not sufficient to represent the atom numbers (and 
Modeller will just 'give up' and write ***** instead). There's 
unfortunately nothing we can do about that, short of writing invalid PDB 
files, splitting the output into multiple files, or writing the 
coordinates out in a non-PDB format (e.g. PDBML, CHARMM, MMCIF).
