Lambda: the Local Aligner for Massive Biological DatA

Lambda is a local aligner optimized for many query sequences and searches in protein space. It is compatible to BLAST, but much faster than BLAST and many other comparable tools.

Downloads are available from the sidebar on the left. Lambda is Free and open source software, so you can use it for any purpose, free of charge. However certain conditions apply when you (re-)distribute or modify Lambda, please respect the license. Also, please cite the publication if you use Lambda anywhere in your academic work. Thank you!

2015-10-23: Release of 0.9.1

Version 0.9.1 has just been released. There is now support for memory-mapped file access to the database which enables sharing the memory between multiple instances of LAMBDA running on the same server. Also the construction of the index now uses a different algorithm which is faster and more memory efficient. See the Changelog for details. Users who built 0.9.0 from Source, please be aware that optimizations where not turned on by default, so please update to 0.9.1 and rebuild. Users of our binaries are not affected.

2015-09-15: Indexes prebuilt for 0.9.*

There are now pre-built indexes for NR, the Uniref databases and the Uniprot databases available in the wiki.

2015-09-14: Release of 0.9.0

I am pleased to announce the availability of lambda-0.9.0. This is the first release based off SeqAn 2.0 with many bug-fixes and new features. See the Changelog for details. Please note that the indexes created with older versions are not compatible.
