How i can find the specific threshold levels.? With 'peakdetection' i can find the specific peaks but how to find particular threshold such as greater than 2,3,4 and 6.? in one large data set.

threshold levels are not just found from the dataset like peaks. You need to give a definition that what type of thresholding you want. It depends on what type of information you want to extract from your dataset. For example, you want to extract all values which lie above mean is one such example of threshold definition.

No i have a data set containing peaks of amplitude 2,3,4,5 and 6. I just need to save them separately with respect to their locations.

[Ameer Hamza]

Can you share an example of your dataset and how you want to separate. Perhaps a picture showing original dataset and what is the separating conditions.

[Star Strider]

How are you detecting the peaks?

[Joana]

I am using [peaks,locs]= findpeaks(x,'MinPeakHeight',2);

Although i need to find the peaks for height 2 3 4 5 and 6. It's repetitively mixed in this data set.

Yeah sure.

In this data set i need to separate the threshold/peaks of same groups.
