Hi

recently i worked out for the geoemtry opitimization using G09 using SO4-2
group
 but it woun't produce the prepin and frcmod file using antechamber.
%chk=SO4.chk
#P HF/6-31g* Opt
 SOO4.pdb

-2 1
 S -0.00011283 0.00009246 -0.00011064
 O 0.19932041 1.39283260 0.48010898
 O -1.31262771 -0.10314457 -0.69076867
 O 1.08864613 -0.35807868 -0.94726862
 O 0.02488683 -0.93179428 1.15814958
--Link1--
%chk=SO4-1.chk
#P Opt HF/6-31G* SCF=Tight Geom=ALLCheck Guess=Read Pop=MK IOp(6/33=2,
6/41=10, 6/42=17)

using command
                 *antechamber -i SO4.log -fi gout -o SO4.prepi -fo prepin
-c resp*

Info: Bond types are assigned for valence state 1 with penalty of 1

Info: the number of the ESP exceeds the MAXESP(20000),extend the size and
reallocate the memory automatically
Info: the number of the ESP exceeds the MAXESP(30000),extend the size and
reallocate the memory automatically
*it runs but doesn't produced the correct prepin file using antechamber*

i want to optimize using G09 and calculate the RESP.


Regards
