This page contains links to databases that are pre-formatted for use with Lambda (so that you don't have to index them yourself). If you have created indexes yourself and would like to share them, you can send us a link.

• Unpacking the file after download is not required; you can use it as-is. However, unzipped files may load slightly faster during search (this depends on disk vs CPU speed).
• Taxonomy information is included in some indexes, see Taxonomic Workflows for more information.
• Memory usage during search is usually Unpacked Size + size-of-query-file ± 10%. The memory usage during the creation of the indexes was higher, around 10x input size.

• Unpack the file after download with tar xf FILE.lambda.tar.gz. The resulting .lambda directory is the index.
• Taxonomy information is included in some of the indexes, see Taxonomic Workflows for more information.
• Memory usage during search is usually Unpacked Size + size-of-query-file ± 10%. The memory usage during the creation of the indexes was higher, around 2.5 * Unpacked Size.
