i am using MM PBSA...while save .prm & .inpcrd files for a co-crystallised PDB file it showed error that the atom types of Chloreine atoms in the ligand were undefined. so i deleted those atoms from the PDB and then i could continue.

......
 
   c o-ordinate resetting(SHAKE) can't be accomplished, deviation too   large.
NITER< NIT, LL, I and J are 0, 1884, 3737, 3339
 Note: this usuaaly is a symptom of some deeper problem with energetics of the system  "
