   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'
