Search the SILVA databases with the Geographic-BLAST server, provided by megx.net. GeoBLAST allows sequence based searches and visualisation of georeferenced rRNA entries on a worldmap.

The new ARB version 5.0 has now been released. This is a major step forward and we strongly recommend that you upgrade your systems. The 64 bit version can now even handle large datasets like the SILVA SSUParc database.

Metagenomics sprang from advances in sequencing technology, and continued improvements are providing data in quantities unimaginable a few years ago. But without concerted efforts, the amount of data will quickly outpace the ability of scientists to analyze it.
