i have 186 brain mri 2d slices (256*215) i want to stack them into 3d array (256*215*186) ?

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

The error message indicates that thisSlice is not a 256x215 size matrix. So if you want to stack it in your image array you will need to resize it.

i have all images of dimension 256*215 but still error

I do have the same error. I am doing my thesis as 3D reconstruction of MRI images. Can you help me? Thank you.

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)
