An example that illustrates the exclusivejoin operator. I₁₁.. I₁₄ are intervals in input track 1, I₂₁.. I₂₃ are intervals in input track 2, while I_r1..I_r4 are intervals in the resulting track after the exclusive-join. The whole interval of I₁₁ remains to become I_r1 in the resulting track, because it does not overlap with any interval in track 2. In contrast, the whole interval of I₁₂ is not included in the resulting track, because it is completely covered by I₂₁ and I₂₂. For I₁₃, the part of it not covered by I₂₂ becomes interval I_r2 in the resulting track. Finally, I₁₄ is being cut by I₂₃ into two intervals I_r3 and I_r4 in the resulting track
