Rename images using counter

Hi All,

I have a matlab script with a loop that includes a python script. This python script generates an image file with the name 'A.tiff' for every run of the loop. The problem is that the new image generated overwrites the previous one but I really want all the images generated everytime the loop executes. I think of renaming the image file after its generated by adding a counter to the file name e.g. A_1, A_2, A_3, etc. I can use the 'movefile = (OldFileName, NewFileName)' but what lines of code can I use to insert a counter into the NewFileName argument?

Thanks for your help in advance.

Olu - you can use sprintf to create the new file name. Something like

 for k=1:10

     % call the python script to generate the A.tiff file

     % create the new file name
     newFileName = sprintf('A_%d.tiff',k);

     % move the file
     movefile('A.tiff',newFileName);
 end

Try the above and see what happens!

You can use num2str() to convert the loop index to a string. With strcat() you can combine 2 strings such as A and loopindex

for i = 1:n

loopindex = num2str(i);

filename = strcat('A',loopindex);

% Add you code

end
