Fig. 5

“Elementary” MSA errors associated with single position-shift blocks. The figure schematically illustrates a “shift” [(a)], a “merge” of the events of the same type [(b)], a “merge” of the events of opposite types [(c)], a “purge” [(d)], a “vertical merge” of two deletions [(e)], a “vertical merge” of two insertions [(f)], a “collapse of independent insertions (CII)” [(g)], and an “incomplete collapse of independent insertions (iCII)” [(h)]. In each panel, the tree and the position-shift map on the left are for the true MSA, and those on the right are for the reconstructed MSA. In each position-shift map, the position-shift block is highlighted in yellow, a red gap was derived from an (spurious) insertion, and a blue gap was derived from a (spurious) deletion. On each tree, the thick branch delimits the position-shift block, and a red lightning bolt and a blue lightning bolt represent an insertion and a deletion, respectively, any of which may be spurious
