Dear Bill,
The -25 will be pixels on a non-scaled image. On a scaled image it depends what your scaling is. So basically it is how much smaller we make the ROI before the next measurement. I assume that your shot pattern is centred in your image. Maybe you could send a link to an sample image?

Hi Dr. Straatman,
Thanks for getting back to me. I'm a total novice with ImageJ and I have never used it before. I've just ran your macro and it seems to be a good starting point. However I'm not totally sure what you mean by 'The value -25 depends on the size of your image and how accurate the measurement has to be. You could do this till the value is < 95% and then enlarge with smaller numbers till the value has become >95% again'.
I've got the dimensions of the paper I used so I'll be inputting those. What should I do with the -25 value? Increase or decrease if the circle is significantly different from the shot pattern?
Best regards,
Bill
