For surface analysis of a sample, I did signal processing and peak detection using inbuilt peak detector .vi . But the problem is in shown peak/valley location... I have attached the screenshot of one run. See there are some peaks(valleys) which are fairly away from the actual graph. I am confused. What might be the reason of this fault? Any idea? red blocks--> peaksgreen blocks--> valleys

threshold peak detection is detecting peak just above the threshold line. I think it is better to write code to find peaks.
