A lineage tree a before and b after error correction. Each node represents a cell instance of a colony growing in a single-cell movie. Notice that in (a) there are branches that do not reach the LT’s last level (i.e., there exist leaf nodes at several levels). In single-cell movies with no cell death events, this tree pattern cannot occur. In the corrected LT of (b), all subtrees reach the last level as expected
