Incompatible columns in the orthologous-repeats table; columns i, j, k are incompatible together as any resolution of the ambiguity for species C in column i leads to an incompatibility
| h | i | j | k | l | |
|---|---|---|---|---|---|
| A | 1 | 1 | 1 | 0 | 0 |
| B | 1 | 1 | 0 | 0 | 0 |
| C | ? | ? | 1 | 1 | 1 |
| D | 0 | 0 | ? | 1 | 1 |
As columns i and k are supported by h and l, respectively, column j corresponds to a weak edge and is removed during phylogeny reconstruction, resolving the incompatibility.
