Does Artemis somewhere provide any clue as to where the error was found when it says "Fit aborted due to errors in parameters and math expressions"? FEFFIT used to highlight the last line successfully read, which was helpful for finding unbalanced parentheses and the like. But I don't see an equivalent message here.

I had to go peruse the code to refresh my memory about why Artemis reports that error message. It seems there are two situations where this message turns up. One is when math expressions have unbalanced parentheses, the other is when Artemis finds discrepancies between the guess, set, and def parameters and the math expressions for the path parameters. One such discrepancies is an unused guess or def parameter; another is the use of a parameter in a math expression without defining it as a guess, def, or set. When I go through the project looking for mismatched parens or for discrepancies in the parameters, I am careful to record every such problem. That's good. Unfortunately, it seems that, when mismatched parens are found, Artemis complains and aborts the fit without telling the user where it found the mismatch. So the bottom line is that Scott is asking me to fix a silly bug, which I will gladly do.
