Dear Hannes,
thank you for your quick answer. I will try that.

>> Dear Amber Users,

>> No one answered to my question in October so I will try to make the

>> I will appreciate any help.

>> Dear Amber Users,
>>
>> I am using MM/GBSA of amber10 to calcluate binding energy of
>> protein/ligand system. There is one Zn atom in the protein.
>> Binding calculation is working fine. But I got "bad atom type:
>> Zn" when I run energy decomposition. And I have already add "ZN" =>
>> 1.22 + 1.400,"
>> to the script of mm_pbsa_calceneent.pm according to the mail list.
>>
>> I have also tried to set MS to a non-zero value in my mm_pbsa input
>> but then I get error massage:
>>
>> Died at /usr/local/amber10/src/mm_pbsa/mm_pbsa_readinput.pm line 354.

>> And the line 354 says:
>>
>> if($r_gen->{"DC"} > 0 && ($r_gen->{"GC"} > 0 ||

>> $r_gen->{"MS"} > 0)){
>> print " Energy decomp is not (yet) possible with GC, AS, NM,
