When I create a function using y-script in the non-linear curve fitter, for example:

tau = kn*t;
E1=(exp(-tau)-1+ tau);
Vext = beta*E1;
alpha = 1-exp(-Vext);

the last two charaters always get deleted when I go to the fit window (in this case parenthesis and semicolon).

I have solved this problem by putting in a comment line after the function definiton with some garbage characters in it-but its still sort of annoying. Does anyone know what might cause this?

Response to Problems creating user defined functions

The problem you are experiencing while fitting with a user-defined fitting function is a bug. To correct the problem, download Origin 5.0 Patch 2 (assuming you have 5.0) and apply it to Origin. Be sure to read the directions provided thoroughly since there is some very important information there.

All downloads are currently located in the Tech Downloads area. Keep in mind that this is subject to change at any time.

Sincerely,
Ryan Toomey
