Dear all,
I have 4D images. Can get thru this link. ( https://drive.google.com/file/d/1qlj_6MIcjdN5a2eZXitvtD5dfGhSdt8t/view?usp=sharing ). https://drive.google.com/file/d/1qlj_6MIcjdN5a2eZXitvtD5dfGhSdt8t/view?usp=sharing
the name file is LiverTS399.mat
how to convert it into 3D?
I tried use this command, but still 4D in workspace
load('LiverTS399.mat')
split = squeeze(cropVol);

split = reshape(cropVol, size(cropVol,1), size(cropVol,2), size(cropVol,3)*size(cropVol,4));
This would give you a 3D volume in which the 4th dimension has been spread out onto the third dimension.
or perhaps you want
split = squeeze(num2cell(cropVol, [1 2 3]));
This would give you a cell array in which each element was a 3D slice.

If you mean you want the i-th 3D frame of the 4D data, then,
frame_i=cropVol(:,:,i)
