How can I calculate respiration rate from a respiration signal based on specific onsets?

Dear Matlab experts,
I have a respiration data and I wish to find a way to calculate the respiration rate in specific epochs that I can manually specify.
Is there a way to do that? or any known toolbox?
Thank you very much in advance, Gil

You should be able to just do that with a frequency-domain analysis by either computing the DFT (via FFT), or using a nonparametric PSD estimator from the Signal Processing Toolbox, periodogram(), or pwelch()

Hi. anyone know the equation to calculate respiration rate?
I try to use this coding but it seem like for the heart beat.
dataset = xlsread('rrest-syn192_data.xlsx','Sheet1','A1:B30000')
s = dataset(:,1)
%y = dataset(:,2)
data = [s];
N1 = length(s)
t=0:1/500 : N1/500-1/500
plot(t,s)
title('Plot of signal')
xlabel('Time')
ylabel('Sample(s)')
[pks,locs,w,p] = findpeaks(data)
a=size(pks)
peak_count = (a/2)
Duration_s = (N1/500)
Duration_m = (Duration_s/60)
total_rate_per_minute = (peak_count/Duration_m)

So far we need to used Digital filtering and wavelet decomposition method to extract the respiration rate?
