The program does not recognize serine as it has a phosphorus atom attached to it which is not present in the definition. I am trying to define phosphoserine as a residue (let's say PSER). Can anyone tell me what all files do I need to edit (what kind of data do I need to look for, to be more specific) in order to make the program recognize this new residue ?Thanks in advance for help.Regards,Ashish Bihani 		 	   		


Otherwise, find a force field that contains parameters already (most force 
fields use "SEP" as phosphoserine, not PSER).
