The third is necessary because algorithms for both multiple sequence alignment and structural alignment use heuristics which do not always perform perfectly. The first two are a natural consequence of most representations of alignments and their annotation being human-unreadable and best portrayed in the familiar sequence row and alignment column format, of which examples are widespread in the literature. The rest of this article is focused on only multiple global alignments of homologous proteins. Manually edit and curate automatically generated alignments.Visualize alignments for figures and publication.Aid general understanding of large-scale DNA or protein alignments.

Multiple alignment visualization tools typically serve four purposes: This page is a subsection of the list of sequence alignment software.
