Alignments as partitions of the set of sites (continued). Toy example (continued) - The example alignment of Figure 1, onto which the partial columns detected by MS4 have been "projected". Some MS4 classes, for instance T0-5, correspond exactly to some equivalence class of the original alignment, while others, like G2-5 form only a subset of an alignment column. Note that other classes, like G1-3, while being partial columns by definition, are not part of this particular alignment.
