Yeah, I've read that, however when I open version 1.42o and go to the curve fitting I don't get the option on the drop down list

I've installed older versions and get the same problem

I am doing something stupid?

Thanks again, Steve

Upgrade to ImageJ 1.42f or later, which adds the ability to fit
user-defined functions to the curve fitting tool (Analyze>Tools>Curve
Fitting).
