Created 4D tumour matrix from cstore using a for loop

for i = 1:200
Tumour(:,:,:,i) = cstore{i}

now to convert this data to a useable form such as nifti and see if I can view it in mrtrix or just look at it directly in MATLAB which might be slow.

Looked at imagesc view of tumour with brain overlay, looks more realistic.  Reshaped it into a strange rectangle though.
