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 '|'
