Dear Dr YAN
i use this code for map the discriminant feature to the brain:
%wcoeff:is the eigenvectors of pca(271633*139)
%w: is the absolute features weight(1*68)
%68:no of discriminant features
new_matrix = reshape(v, 73,61, 61);
out.vol = new_matrix;
% write to a nifti file
err = MRIwrite(out,'new_matrix.nii','double');
My result was:
after i moved the cursor the result was:
My question:why the volume its size is very very small?
your help is appreciated.
