To whom it concerns,
I’ve been using antechamber as part of a university project. I’m away from the university for the next few weeks and have downloaded chimera on my mac. I was using chimera on linux in the university. 
Im having the same issue, irregardless of what molecule i have, which is dock prep / add charge. I’m following the same procedure as i did in the university with molecules i know add charge did work for, but am receiving the following error;

Charge model: AMBER ff99SB
Assigning partial charges to residue TAG (net charge +0) with am1-bcc method

Is there anything possible wrong with the general settings in the program that have to be changed? i have literally installed chimera, and changed no settings thus far. I have looked up forums relating to similar issues but have no found a solution.

Any help would be highly appreciated, 
thanks in advance,
