Hi. This may be easy for some Matlab users. I am trying to dicomread and process images starting my code with the following commands:
[Filename1,Pathname1]=uigetfile('Multiselect','on');
for i=1:length(Filename1)
images(:,:,i)=dicomread(fullfile(Pathname1,Filename1{i}));
images=double(images);
end
However, my images appear to change size therefore I get the error: 'Subscripted assignment dimension mismatch.'
Any ideas how I could dicomread and place in order all dicom images independently of their size, would be much appreciated.
Thank you

You've answered your question in its title. Use a cell array:
[Filename1,Pathname1]=uigetfile('Multiselect','on');
images = cell(size(Filename1));
for fileidx = 1:numel(Filename1)
images{fileidx} = double(dicomread(fullfile(Pathname1,Filename1{i})));
end

I'm not even sure that you NEED to have all the images in memory simultaneously. Why do you think you do? Usually it's not necessary. Just process each image one at a time in the loop and don't store them all.

I re-sorted my files, tried again and it worked (I am not sure why I got this error in first place).
I think that I have mis-used the term 'cellarray', instead of using 3D matrix initially but your are right, I can replace the 3D matrix with a cellarray. I only need to incorporate changes in a relatively long code, but there is no free lunch in life.
Thank you again both.
