I have some troubles with my code. While i'm trying to open my fire pixels datas, I receive the message "index exceeds matric dimension" but I don't understand where it come from...
9- [contenunum, contenutext] = xlsread('Maghreb_0218.csv');
11- nb=numel(contenunum(:,1));
13- fifi= datevec(contenutext(2:nb+1,6),'dd/mm/yyyy');
14- fifi_lat=str2double(contenutext(2:nb+1,1));
15- fifi_lon=str2double(contenutext(2:nb+1,2));
16- fifi_bright=str2double(contenutext(2:nb+1,3));
18- CAD_FEUX=cat(2,fifi(:,1:3),fifi_lat,fifi_lon,fifi_bright);
Index exceeds matrix dimensions.
Error in MODIS_FEUX (line 11)
The size of contenunum is 1,10 and contenutext is 1,11.
The thing is the same code is working with the same datas for my colegues but not for me...
Hopefully someone will be able to find the problem...

Please attach your file Maghreb_0218.csv.
It seems that contenunum variable is empty
Yes the variable is empty but I don't know why... I have linked the file to this messsage.

T = readtable('fire_archive_M6_59116.csv');
a = T.acq_time/100;
T.acq_date = T.acq_date + hours(fix(a)) + minutes(100*mod(a,1));
T.acq_date = datetime(T.acq_date,'F','uuuu-MM-dd HH:mm:SS');
T_out = [T(:,6), T(:,1:3)];
