Find Peaks tool

[jcamilleri]

Hi all,

I am new to the forum, so my apoligies if this problem has already been dicussed. I am trying to find the first 100 highest peaks from a pressure time trace which is basically a series of impact events (see Figure) using the Find Peak tool. My problem is that the algorithim is recognizing 'secondary' peaks from the same imapct event. I was thinking of first filtering the signal to remove the high frequency noise and 'secondary' peaks and then use the find peaks tool, but the magnitude of the peaks is important. So I would need to go back to the original time trace. Any ideas? 

Thank you.

Hi Josef,

I think if yours pressure/time impact traces are always the same length (in terms of time), you could use the calculate peaks function in analysis and set your interval width and lower limit values so it would not pick up the secondary peaks.
