Yes. The g98 job complete successfully. I found these word at the end of the
g98.log file " Normal termination of Gaussian 98." The input for g98 is as
followed and the input coordinate file was generated with antechamber
"antechamber -i x.mol2 -fi mol2 -o g98.gcart -fo gcart".

gp8.inp goes here
"%chk=gausesp.chk
#HF/6-31G* SCF=tight Test Pop=MK iop(6/33=2) iop(6/41=10) iop(6/42=6)

remark line goes here

-2 1
 45 atoms' coordinates."

THen I used the command line: " antechamber -i g98.log -fi gout -o resp.prepi
-fo prepi -c resp -s 2 -nc 2 " to calculate RESP charges. The resp.prepi file is
as followed. The residue fragments don't have charges and angle values. ANd the
torsion values are also strange.

 resp.prepi file goes here:

0 0 2

This is a remark line
