How to analyze different segments in a timetable?.
2 views (last 30 days)
Hi I have a timetable with different physiologic measurements (example attached).
The first column is duration in seconds, and the last column is a time marker that means: 0 is off and 5 is on. When time marker is on, means that the recordings corresponds to the experiment. The other columns are physiological variables as the figure shows.
As the Time Mark shows we had 10 experiments. I would like to have advice on the best way to extract the duration of every experiment.

Try this —
LD = load('timetable.mat');
AB001 = LD.AB001;
ExptMarker = AB001.fTimeMark; % Marker Vector
Lv = ExptMarker>0; % Logical Vector
ExptStart = strfind(Lv', [0 1])+1; % Start Indices
ExptStop = strfind(Lv', [1 0]); % Stop Indices
ExptIdxMtx = [ExptStart; ExptStop]'; % Index Matrix
ExptTimes = AB001.time(ExptIdxMtx); % Time Matrix
ExptDuration = ExptTimes(:,2) - ExptTimes(:,1) % Duration Vector
10×1 duration array
