Dear Amber users,
I've got an error during use of antechamber with Divcon module. I use suse 11 system 64 bit and I've installed amber with ifort-64. Amber version is Amber 9.

 "Error: cannot run $AMBERHOME/exe/divcon of bcc() in charge.c properly, exit", and the divcon.out file is also in attachment for your consideration.
MAXIT can be reached because of installation problems, right? If I need to change MAXIT (as posteed here http://archive.ambermd.org/200606/0019.html ), which file I need to modify? How to check if net charge is proper? (if to use this answer http://archive.ambermd.org/200606/0019.html).

Best regards,
Andrew

Below is divcon.out The pdb file of ligand and divcon.in are attached:
