Dear David,

thanks for your response.

I am running Ambertools16 on CentOS. I am not sure on the compiler,
since I run this on a remote system and I did not install Amber myself
myself. Any suggestion on how to check for this? I am currently
installing AmberTools on my own system to see if I can reproduce the error.

I also receive this error message:

Running: /share/apps/amber16/bin/atomtype -i ACDOCTOR_BOND.ac -o
ACDOCTOR_ATOM.ac -p gaff
Cannot open the ac input file: ACDOCTOR_BOND.ac, exit
Error: cannot run "/share/apps/amber16/bin/atomtype -i ACDOCTOR_BOND.ac
-o ACDOCTOR_ATOM.ac -p gaff" in main() of antechamber.c properly, exit

Kind regards,
Andreas
