But that should not be a problem for you. Once the topology is specified,
you can use psfgen with your pdb file to create the required psf. This way,
it is automatically taken care of for every molecule. This should work:

topology all.rtf
segment TIP3P {
 auto none
 pdb wat.pdb
}
coordpdb wat401.pdb TIP3P
writepsf wat2.psf
writepdb wat2.pdb
