I extract this line from my file : {'1;158.798;281.117;99.858;39.855;2182;'} and Next step is to extract the second , third , fourth and fifth numbers like this : [158.798,281.117,99.858,39.855]
Any help please ?

>> C = {'1;158.798;281.117;99.858;39.855;2182;'};
>> D = regexp(C,';','split');
>> D{1}(2:5)
ans =
'158.798' '281.117' '99.858' '39.855'
>> str2double(D{1}(2:5)) % convert to numeric
ans =
158.798 281.117 99.858 39.855

Hello again Stephen, Can you help me please , ? I need to add a header to my textfile and this is my code :
for k=1:nbrRect
Cellule{k}=get(rectangles(k), 'Position');
tag= CellTag(k);
x1 = Cellule{k}(1)+Cellule{k}(3)/2;
y1 = Cellule{k}(2)+Cellule{k}(4)/2;
fprintf(fileID,'%d;%5.3f;%5.3f;%5.3f;%5.3f;%d;%5.3f;%5.3f;\n',tag,Cellule{k}(1),Cellule{k}(2),Cellule{k}(3),Cellule{k}(4),numf,x1,y1);
end
I added this line before fopen and the boucle for but there is no header in my file:
fprintf(fileID,'%d;%5.3f;%5.3f;%5.3f;%5.3f;%d;;%5.3f;%5.3f;\n','Person ID','pos1','pos2','Width','height','X centre','Y centre');

"I added this line before fopen and the boucle for but there is no header in my file"
That line will need to go after fopen and before the loop. You will also need to change the all of the format specifiers to %s.
