Hi all,

 

We use peakforce QNM to get the mechanical properties for our sample. I have a question about the machanical properties fit region from the force curve. In default option, why the mechanical properties are calculated using the retraction part from the force curve, but not the approaching part from the forca curve?(as shown below)

I would greatly appreciate your any help. Thanks.
