Hi Brad,
I am cc'ing this to the chimera list.
I think that you should write a python script to run DOCK prep on the command line. See the following:

For other example scripts see the following:

You should not have to specify the AMBERHOME path. This is done internally to chimera.
as an aside, It is unnecessary to run antichamber with sudo.
I hope this helps,

Hi Dockfans,
My name is Brad; I am a grad student in the dept. of chemical engineering at Purdue University.
We are experimenting with DOCK for various drug discovery work. At the moment, I am trying to do execute all of the "dock prep" commands through the Terminal, since it is not practical to do large volumes of Dock Prep by hand through the CHIMERA GUI.
Corresponding to what is in the DOCK tutorial, I am on "Receptor and Ligand Preparation." I got reduce to work, in order to add hydrogens.
Now, I am trying to get antechamber to work, in order to add the charges, but it is not working. Here is the command I am running:
sudo ./antechamber -i $DESKTOP/3GLR.pdb -fi pdb -o $DESKTOP/ 3GLRcharged.mol2 -fo mol2
Which returns the error:
Warning: $AMBERHOME and $DOCK_HOME enviornment strings are not set, use "mopac.sh" in the work directory
Cannot open CONNECT.TPL , exit The atom number exceeds the MAXATOM, reallocate memory
I looked around in the dock6 directory, and found a folder called "parameters/antechamber", which contains CONNECT.TPL. I figured this is what should be the $AMBERHOME directory. For DOCK_HOME, I figured it should be the dock6 folder.
Here is what I have in my .bash_profile file in my home folder.
export AMBERHOME='/home/.../DOCK6.5/dock6/parameters/antechamber' export DOCK_HOME='/home/.../DOCK6.5/dock6'
I also tried using the "amber11" folder that comes with CHIMERA as AMBERHOME, but to no effect.
I don't actually have AMBER installed on my computer, but since CHIMERA can add charges without actually requiring the purchase of AMBER, I do not think that is the problem.
I did not know what to do with "mopac.sh." I ran the script, but it says it needs input files.
What am I doing wrong that is preventing antechamber from executing correctly?
