Find only the top peaks

I have an array in which I wish to find the value of the top most peaks. Using findpeaks finds ALL of the peaks, there is alot of noise in the data which produces over 5000 peaks. Even if I remove the low freq noise there is still noise in the top most peaks. I only want the top '36 peak' values:

Thanks

 pks = findpeaks(data, 'MinPeakHeight', 3.5);
