 Splitting tracks by position
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-When the target sites of the protein are known, the binding lifetimes can also be split by position and analyzed separately[1]_.
-For example, to select all tracks from `kymo1_selection` that have an average position larger than 8 micron, type: `track_selection = tracks1[[np.mean(track.position)>8 for track in tracks1]]`.
