Good morning to everyone. I have a set of data that is named data13. I need to extract peaks that are higher than a certain value named TWS. 
I used this function that works, but in data13 have different local peaks.
PEA1 = FindPeaks[data13, 0, 0, TWS];
I receive as answers all the peaks that are higher than TWS.
Is it possible to have only the highest one, over for example a certain length?
Thank you very much for your help.
