Multipath intervals. Illustration of two genomic features represented by single-path intervals (orange and blue). Assuming that which paths are taken between A and E is irrelevant, as long as they go through C, both can be represented by the same critical multipath interval A ₀,E ₀,critical=C. The same can be achieved by using a fuzzy interval with either of the two singlepath intervals as a main path and a threshold of 2, since the edit distance between region path C and F is 3. Note that if using a threshold of 1, both region path B and B ^∗ cannot be contained in the same multipath interval
