Finding peaks in a data set

Hello all,
I have some data and need a way to reliablly find the peaks of the data set. The picture below shows the plotted data. There are 19 peaks on each side of the data for a total of 38 peaks. I have tried using the findpeaks function, however it seems to pick up random spots in the data. I am consisently trying to find all 38 peaks.

Thanks

And, I suppose while we're asking, what options did you use/have you tried to rid the spurious peaks from the results???? findpeaks does have quite a lot of flexibility in what it thinks is a qualifying peak depending on the inputs given.

I would first ensure you are using MathWorks' findpeaks(). If you enter
>>which findpeaks
do you get something back like
matlab\toolbox\signal\signal\findpeaks.m
If so, then as dpb suggests, I would use one or more of the options in findpeaks() like
'MinPeakHeight',MPH
for example.
