Unforntunately for the recommended group M Archaea primer a wrong primer pair was shown. The corresponding paragraph has been corrected. Please update to the latest version of the paper. [more]
Today we finally release a major update for TestProbe and the SINA aligner. We also refactored the way the submitted jobs are controlled by implementing a "TaskManager" and fixed some bugs to generally improve the speed and quality of service SILVA provides.[more]
File Exports, Sequence Alignment, TestProbe and TestPrime offline from 4 PM GMT (12 PM/Noon Eastern, 6 PM Germany).[more]
The results of the evaluation of general primers for 16S rDNA amplification have now been published in NAR. Many thanks for your support.[more]
Taxonomic ranks mapping file for the new SILVA eukaryotic taxonomy is now ready! Please have a look at the ETWG project page for more information and for downloading the spreadsheet file.[more]
Due to some missing data in the fields bio_material, country, pcr_primers and tax_xref_embl in the ARB datasets we updated all ARB files.
Also a new version of the non-redundant (NR) SSURef dataset based on SILVA 111 is available. Please note that you can now even restrict your searches in the web db to the current NR subset!
Finally it is done: SILVA 111 is released. 3,500,000 rRNA gene sequences and a heavily revised eukaryotic taxonomy.
TestPrime is a new tool that allows you to evaluate the performance of primer pairs by running an in silico PCR on the SILVA databases.[more]
