Diagrams showing the 2D-overlap and 1D-overlap of synteny blocks. Dm and Nm are the distance cutoffs that were used to correct the boundaries of the synteny blocks (dashed lines denote new boundaries). The correction of block boundaries allows more efficient implementation of overlap detection in both chaining and screening of synteny blocks.
