Using a boolean operation to assign specific values for each threshold

Hi,

I have a data that has noise in it and I want to convert it using boolean operation assigning specific integers based on the set threshold. So for example, based on the plot below I want to set 4 thresholds corresponding to 150-750, 750-1500, 1500-2250, 2250-3500. Based on these 4 threshold I want to use boolean operation to assign integers that correspond to each threshold. So for any value between

>150 & < 750, I want it to assign and store a 1

>= 750 & < 1500, I want it to assign and store a 2

>= 1500 & < 2250, I want it to assign and store a 3

>= 2250 & < 3500, I want it to assign and store a 4

I will eventually want to sum all the number of 1s, 2s, 3s and 4s to tell me the peaks for each threshold. Using findpeak on this data even when using a filter gives me data I don't need. I rather do it this way. Please any advice is appreciated. See attached data.

Use the discretize function.

Thank you it worked
