my code has an error at this line image(:,:,slice) = thisSlice; dimension mismatch help me to solve this problem

numberOfSlices=186;

image = zeros(256,215, numberOfSlices);

for slice = 1 : numberOfSlices

 files = dir('C:\Users\MuhammadFaisal\Desktop\finalimage(117-1) output/*.png');
 dir_name='finalimage(117-1) output/output_slice_';
fullFileName = fullfile('C:\Users\MuhammadFaisal\Desktop\finalimage(117-1) output',num2str(slice),'.png');
    thisSlice = double(imread(strcat(dir_name,num2str(slice),'.png')))/255;
     image(:,:,slice) = thisSlice;

end

Type the following at the command line:

dbstop if error

Then run your code. When the error is encountered the code will pause in the debugger with all current workspace variable values intact. Then do this to see what you really have:

size(thisSlice)
