Hi Deepti
I doubt if you can run gaussian job within amber. The gaussian input
file you have got from antechamber can be submitted to gaussian
program to get the output file.
Here is how I did for my system >>>
------------------------------------------------------------------------------------------------------------------
I generated the gaussian input file using antechamber, as
follows:
% antechamber –fi mol2 –i DMPC_mono_sybyl.mol2 –fo
gcrt –o DMPC_mono.com
Then, using the generated input file, I ran a gaussian job,
as follows:
% g03sub –n 1 DMPC_mono.com
Then I used the gaussian output in antechamber to do the
2-stage RESP fitting as follows:
% antechamber -rn DMP -fi gout -i H1DMPC_mono.out -fo prepi
-o DMPC_mono_resp.prep -c resp -s 2
This gave me the prep file, which I checked using PARMCHK
utility, as follows:
% parmchk -i DMPC_mono_resp.prep -f prepi -o
DMPC_mono_frcmod
------------------------------------------------------------------------------------------------------------------
Hope this helps. Please correct if I am wrong.
Best, -Akshay

Subject: Re: AMBER: antechamber for topology file
thank u so much for the help. im using antechamber now to generate
topology file. i wanted to know how to run gaussian in amber?? what is
the command? i have a gaussian input file which i got after running in
antehamber. nw i want gaussian output file and for that purpose i have
to use gaussian. bt i dont know how??
plz help
