When the below code was used with a different set of data, it worked fine but when I use a different set, it gives the following error:
Data set must contain at least 3 samples.
There is more than enough data (over 1 million) so this shouldn't be a problem. How should I go about fixing this?
start_time = filteredTT.x(1);
end_time = filteredTT.x(end);
interval = minute(1);
idx1 = start_time;
breathingRate = [];
time = [];
while idx1 < filteredTT.x(end)
range = timerange(idx1, "minutes");
data = table2array(filteredTT(range,:));
timeperiod = (filteredTT.x(range));
[pks, loc] = findpeaks(data, timeperiod, "MinPeakDistance", seconds(3));
numOfPeaks = size(pks,1);
breathingRate(end+1) = numOfPeaks;
idx1 = idx1 + minutes(1);
end

Thank you for your comment. The number of columns are always the same. The only thing changing is the number of rows for the data that is being passed.

you would get that if there is any location in the data with fewer than 3 entries in the same minute.
