How to do slice timing on SPM

Hi,

When we have interleaved acquisition, how can we do to make a good slice order?

And how can we do to choose a slice reference if we have 44 slices and TR=3s.

What is the goal of this vector and how can we use it??

slice_order=[];
for k=1:round(sqrt(nslices))
slice_order=[slice_order k:round(sqrt(nslices)):nslices];
end

You appear to be asking a question about the SPM package, rather than a question about MATLAB.
