slice index will be used of the protocol;</br>
where the <code>&lt;endslice&gt;</code> is the end slice index will be used of the protocol, so the slices from <code>&lt;startslice&gt;</code> 
to <code>&lt;endslice&gt;</code> will be used in this protocol;</br>
let's take a look on the second <code>&lt;collimator&gt;</code> of the above sample,</br>
where the <code>&lt;mergescale&gt;</code> is the scale of slice merging, in this sample protocol '16x0.5' will use 
the 5th to 20th slices and don't merge them;
