Remarks

  • Upload or paste your sequences to align them according to the official ARB/SILVA rRNA alignment.
  • Output files can be downloaded in the .arb format to easily supplement your personal ARB/SILVA databases.
  • To get all information provided by the webaligner, please make sure that you 'Opens internal link in current windowScan for Unknown Fields' in the "Species Information" window of ARB.
  • Next relatives are taken from the SSU/LSURef databases which contain all sequences >1200 bases. They can be used for a Opens internal link in current windowquick phylogenetic classification of your sequences.
  • The amount of sequences for alignment using the SILVA Webaligner is limited to 300.
  • More information about the SINA Webaligner can be found in the Opens internal link in current windowbackground section.

Beta aligner

To merge ARB files generated by the aligner on the beta.arb-silva.de page with the SSU or LSU ARB databases you have to convert the field "align_quality_slv" from f0 (float) to i0 (integer).

To do so, open the database with your aligned files in ARB, toggle to expert mode (ARB_NT -> Properties) to access the "Convert fields …" option in the SPECIES INFORMATION window (-> FIELDS -> Convert fields).
