readtable().

In your version, those durations will come across as character vectors, and you will not (in your version) just be able to pass them to duration() in order to convert to HMS. However, you can

cell2mat(cellfun(@(s) sscanf(s, '%d:%d:%d', [1 inf]), Table.Variable, 'uniform', 0))

and pass that to duration() [you might have to split the columns into individual arguments.)

Thanks for your responce.

But it shows error.

If i change the time with numerical values then how it works. if posible send to me details programme.

Time Allystar M8T F9P LS

2 -0.3784 -0.0922 0.0863 -0.1232

Eek, your version was pretty primitive on reading table formats compared to current versions!

filename = 'allystar.txt';
fid = fopen(filename, 'rt');
tcell = textscan(fid, '%s%f%f%f%f', 'headerlines', 1);
fclose(fid);
t = table(tcell{:}, 'variablenames', {'Time', 'Allystar', 'M8T', 'F9P', 'LS'});
timeparts = cell2mat(cellfun(@(s) sscanf(s, '%d:%d:%d', [1 inf]), t{:,1}, 'uniform', 0));
t.times = duration(timeparts(:,1), timeparts(:,2), timeparts(:,3));
plot(t.times, t.Allystar, t.times, t.M8T, t.times, t.F9P, t.times, t.LS);
legend({'Allystar', 'M8T', 'F9P', 'LS'})
