BACKGROUND_
The rapidly increasing number of available rRNA sequence data and the growing importance of rRNA based identification systems as well as the missing of an integrated package of cooperating software tools for data handling and analysis led us to establish an interdisciplinary bioinformatics group.
The ARB project (latin, "arbor"=tree) was started as a joint initiative of the
Lehrstuhl für Mikrobiologie
and the LRR of the Technische Universität München in 1992.
Since 2014 the ARB project is continued by the
Department of Molecular Ecology
at the Max Planck Institute for Marine Microbiology in Bremen
in cooperation with
Ribocon GmbH.
The ARB software is a graphically oriented package comprising various tools for sequence database handling and data analysis. A central database of processed (aligned) sequences and any type of additional data linked to the respective sequence entries is structured according to phylogeny or other user defined criteria. Take a look at some features. To get a quick impression, see how we presented ARB on several conferences.
The entire software along with the databases can be used by scientific community for free. See Copyrights for details.
Ribosomal RNA Database_
Manually curated and quality checked datasets for ribosomal RNA genes are available for the scientific community. These datasets are maintained in collaboration with "arb-silva" project and can be obtained from ARB Silva Database site.
