Subject: AMBER: ESPGEN problems to read G03 output files

From: Hernán Alonso (

Hi there,

I am new to Amber and I've been trying to set up a topology file for an
organic molecule. I have done some QM calculations with gaussian to
obtain the ESP point charges. After getting the gaussian output file I
tried to extract the EPS charges using ESPGEN, unfortunately the
program doesn't seem to work, it just does not generate nothing nor it
gives any errors.

Has anyone found this problems before?

Can ESPGEN handle any G03 output?

gaussian03 imput:
# b3lyp/cc-pvqz scrf=(iefpcm,read) guess=read geom=checkpoint Pop=MK

If there could be a problem with the format of the gaussian output
file, how could I re-format it so that it is recognized by ESPGEN.

I'm sending the g03 output file as an attachment.

Thanks 1000,
