Hi. I am not very used to textscan and I really do not understand the help text. I have a textfile with A lot of text before the actuall data starts: " HL) [EOH] [BOD] 20111006 0:00,1210,134,98,984,7.83,235,2.47," etcetra with more columns. 20111006 0:10,1209,135,98,989,5.83,234,6.47," is next row and so on.
How can I with textscan only get the time in the beginning and remove all text before data starts, and remove all data after the time.
Any suggestions?
Thank you!

[EDIT]
for the case when nameyourfile.txt contains data in the form:
'20111006 0:00,1210,134,98,984,7.83,235,2.47'
'20111006 0:10,1209,135,98,989,5.83,234,6.47'
fid = fopen('w3.txt');
d = textscan(fid,'%8s %5s %*s');
fclose(fid);
out0 = [d{:}];
t = cellfun(@(x)strcmp(x(end),','),out0(:,2));
out0(t,2) = cellfun(@(x)['0' x(1:end-1)],out0(t,2),'un',0);
out = arrayfun(@(x)[out0{x,:}],(1:size(out0,1))','un',0);
