Purpose: Premade alignments provide curation and codon alignment to produce cleaner alignments than those you can get directly from our search interfaces. We create several different types of alignments that serve well for a variety of purposes. For details, see Sequence Alignment Help.
* Alignments are named for the year in which the sequences were published. For example, “2020” alignments contain sequences published through the end of 2020. The Compendia are published the year after the sequences were published, so the 2008 alignment appears in the 2009 compendium.
** User-defined ranges are clipped from a genome alignment. This option is available only when genome alignments are available .
