A most basic example of a reference/donor graph, constructed from the superposition of the two original graphs. (a) Reference graph G
. (b) Donor graph G
. (c) The graph representing the reference sequence "TTGTTATTCTAC" and donor sequence 'ACGTTATTCTGT'. The donor subsequence "GTTATTCT" is reference-parallel, with reference marker R[3: 7], indicating that it aligns to position 3-7 in the reference sequence.
