Retracting the time-tags from the histcounts
1 view (last 30 days)

A histogram (number of time-tags per unit bin) was created using "histcoounts" for a series of time-tags (first picture). After creating histogram, I put the threshold (300) on the count such that the values below the 300 shall get deleted. And the time-tags should be retractable for those values that were above the threshold. Could you please help me with getrting the values of time-tags from the second picture?

If you are working with R2019a or a later version, use readmatrix and writematrix. Otherwise, use writetable
D=readmatrix('timetags.txt');
%transposing as histcounts() returns a row vector
D1=histcounts(D, 'NumBins', 200).';
subplot(2,1,1);
plot(D1)
subplot(2,1,2);
D2=D1;
D2(D2<300)=[];
plot(D2)
%write data to a text file
writematrix(D2, 'tagtime.txt')
%check the contents of the file
type tagtime.txt

Try setting those counts to nan. Then they won't show up. Something like
data = 5000 * rand(1, 5000);
subplot(1, 2, 1);
[counts, binEdges] = histcounts(data);
plot(binEdges(1:end-1), counts, 'b-')
yline(300, 'r-')
counts(counts <= 300) = nan;
subplot(1, 2, 2)
plot(binEdges(1:end-1), counts)
grid on;

Could you supply the data and code for your picture above?
