An example workflow of LineageSpecificSeqgen. For each tree, the program creates a random root sequence according to the parameters specified. The program then evolves the sequences, according to the parameters given for the root, along the subtree beneath the root (excluding parts of the tree that are beneath events). The resulting sequence at each event is then used as an ancestral sequence for the subtree beneath that event, and the sequences are evolved along that subtree according to the parameters specified for that event. The output is an alignment of the resulting sequences at the tips.
