feature extraction of Raman spectrum finger print

If I have the data of Raman signal which is a plot between amplitude and wavelenght, and I want to make a feature table to classify the substate. Here is the example from my data (just 1 class). If I have another class which is different shape from this plot, so what should I choose to extract from the data?

You have to pick the peak (x,y) values.....there are four peaks..so you will get respective peaks (x,y) i.e wavelength and amplitude values. Read about findpeaks to extract the peak values.

TY for your reply, you mean I have to find the number of peak and peak value that respects to wavelenght and amplitude right?
