Channel Peak Detect

[sirwin]

I wrote a script to find the indexes of all valleys in my data set. I call ChnPeakDetect to do this:

Call ChnPeakDetect("/Time", "/accelChannelXFiltered", "/PeakPositions", "/PeakAmplitudes", "Valleys", -29.43, 100) 'Peak detect to find impact pulse

I validated my code against a known good data set and verified that the detected valleys are correct.

I have a new data set that is very similar to my known good. My script fails to find the valleys in the data.

I attached both the good and bad data sets.

Any ideas why my script fails to find the valleys in the bad data?

Hi sirwin,

try to reduce the width from 100 to e.g. 10.

A nice description about the required width is given in the help for the ChnPeakDetect - command.
