[AMBER] Antechamber: generating prep file

Dear Amber users,

I want to simulate a protein with inhibitor molecule. As the inhibitor
molecule is from the crystal structure, we thought to get only ESP charges
from Gaussian without any optimization (with POP=CHELPG). The log file of
our gaussian run completed successfully. The log file is attached for your
reference. When i feed this log file in antechamber, the produced prep file
is not taking the charges in gaussian log file, instead giving 0.0000. A
part of prep file is shown below.

 0 0 2

This is a remark line

   8 C4 c3 M 4 3 2 1.546 41.376 42.779 0.000000


i run the antechamber with the following command.
antechamber -i gaussian.log -fi gout -o xxxx.prepin -fo prepi -c esp

Kindly help me to solve this problem.
