Hi Joshua, Thank you for your answer. So you're saying that we can simultaneously define FOLP for each potential type in the way you showed, right? Then is there any rule of thumb on what appropriate numbers should be used, like what are for anions and what are for cations, what are for ionic bond and what are for covalent bond? thanks. best, Enyuan On Sun, Nov 25, 2012 at 1:00 PM, wrote:

Hi every one

I am trying to do peak fitting on Athena. Whenever I choose the error function and click "fit" the software crashes, but it works fine when I choose arctangent.

Just wondering if anyone encounter the same issue too, and whether I'm missing something during the fitting process. Thanks!

Regards Linda
