Reject small peaks in Multipeakfit

hi

It seems that Multipeakfit is a much more powerful tool than the early findpeak based routines...

I was wondering whether there was a simple way to add a constraint to all peaks similar to the /M option for findpeak?

I would like to avoid including in the fit small "bumps" in the data
If you are getting narrow peaks from picking up noise, you can adjust the smoothing factor. If you are getting small (low amplitude) peaks you can adjust the min fraction.

These adjustments are, by default, hidden in the Multipeak Fit panel. Below the Auto-locate Peaks Now button you will see a small disclosure control. Click that and you will see three new settings: Noise level, Smooth Factor, Min Fraction. Most likely you want to increase "Min Fraction".

Thank you John

I had missed the little arrow to see the setvariable for those parameters...
