Several Peaks with GPF

[Reepicheep]

Hi Guys

I've got the following problem:

I receive data from a spectroscope. Within this curve I've got several peaks I have to extract with the "Gaussian Peak fit vi".

At the end I need the positions of two peaks in a specific area.

How can I sort the data? Is it possible to filter just some parts out (e.g. in a specific Wavelength-area [scale X])? Or is there a function to display more than one peak?

I don't want to use the "Waveform Peak Detection vi"!

I hope, somebody can help me. And if I was unclear with the question, just ask...

Thanks in advance

I also tried to split the x array, but that didn't work properly... No tipp or anything?!?

Hi CSEM,

I am not sure, if i have understood your question right, but if you just would like to detect the peaks in a waveform, why don't you want to use the peak detector.vi (dbl, not waveform)? Do you have the LV Base package? If not, there is an example "Peak detection and Display", which could give you an idea.

Regarding filtering you datas? Do you mean extracting sample points? tHis could be done with the array function "delete from array.vi".

If this doesn't help, please provide a little bit more info's or post a data set and your vi you have.

With Best Regards,
