In a, the union of colors is computed within the solid regions around the non-solid region to correct and the USNMs. This union will partially guide the graph traversal, along with the sequence similarity of the paths to the non-solid region. In b, a first subgraph (highlighted in red) of all paths starting at unitig us with Pmax=2 unitigs is explored for correction. The lower path is extended using the same method (shown in green) and a path connecting to un is found
