Hi,
After I got DMT modulus image, how do I analyze the image? Such as the average value of DMT modulus? Do I need to flatten the image?
Thanks!
Fangfang
sorry, Fangfang, I made a mistake in my last reply, you can check mean value in roughness analysis for the average modulus.
Hi, Fangfang,
You should not flatten modulus image, it will change your data. To get average, you can simply use roughness function to get Rq and Ra for your analysis.

Hi Fangfang,
Use the Bearing Analysis function of Nanoscope Analysis. Define the area (draw a square with the mouse) to be processed and click execute. You will get the histogram distribution and the average value. Note that you can do this with any channel. Ang is right: be very careful with the flattening orders; this can screw up your original values.

hi Ang Li,
may I know if there's any way to to extract the exact shape of the particle from the image and get the average modulus value? So far the only method I know is draw a box on that sample and get the value but then I lost most of the particle surface. I don't think the modulus value represents the whole sample. Is it?
Hi, Solverra,
If your particles can be recognized in the modulus channel, you can try particle analysis function to get the averaged modulus value of each particle. Besides this, bearing analysis may also help to get the overall average modulus depending on the contrast of your particles in the modulus channel. If you need further help, you can send your file to my email here: ang.li@bruker-nano.com.
