Subject: AMBER: antechamber problem using RESP

Dear All,

I am trying to calculate the partial charge of CH4 using antechamber
with RESP option. I generated the Gaussian 03 input file with:

antechamber -i ch4.pdb -fi pdb -o ch4.com -fo gcrt

I got:

--Link1--
%chk=MOL
#HF/6-31G* SCF=tight Test Pop=MK iop(6/33=2) iop(6/42=6) opt

remark line goes here

0 1
    C 0.0000 -0.0000 0.0000
    H 1.0920 0.0000 0.0000
    H -0.3650 1.0290 0.0000
    H -0.3640 -0.5150 0.8920
    H -0.3640 -0.5150 -0.8920

This input file works well with Gaussian 03 and I got the ch4.log
file. But I get some problem with:
antechamber -i ch4.log -fi gout -o ch4.mol2 -fo mol2 -c resp -s 2

Here is the error message:

 Amber8 Module: resp

? FORTRAN Runtime Error:

Does anyone know the source of this problem?

Many thanks,
