PR2 Shiny application

Here is a short description of the different panels

Taxonomy

Listing of taxonomy used for PR2 with number of sequences for each species

  • First Select Taxa on the left Menu by navigating the menu
  • Once you have selected the taxonomy press VALIDATE TAXA and you should see the table of taxons
  • To reset the taxonomy press RESET TAXA followed by VALIDATE TAXA.
  • You can save and reload your favorite taxa on the bottom left of the screen
  • The table can be searched and filtered
  • If you click on species name, you are redirected to the GBIF page if it is available
  • Additional columns provide functional traits (e.g. Harmful Algae Species, Mixoplankton etc…)



Sequences

Listing of PR2 sequences for the selected taxa with the following information provided.

You can filter on the left menu the sequences by:

  • Gene: 18S rRNA, 16S rRNA (for organelles) or Full operon (ROD database version 1.2)
  • Only reference sequences
  • Length
  • Only Harmful Algae Bloom (HAB) species
  • Only Nixoplankton species
  • Type of samples: corresponds to sample origin as detailed in the GenBank record or the original paper
Type Origin
culture Well-defined culture
environmental e.g. oceanic water or soil
isolate Organism isolated for example by pipetting but not in culture
specimen e.g. from a plant species
unknown no information available

The following information is provided:

  • PR2 accession number
  • Gene
  • PR2 species assignment
  • Sequence length
  • Sample type as annotated by PR2
  • Definition and Taxonomy provided by GenBank



Download selected sequences

Download PR2 sequences and their metadata for the selected taxa

You can filter on the left menu the sequences as explained in previous section.

The description of the files is provided on the page.



Download full database

Download full database if you use PR2 to annotate metabarcodes.

Files are provided for: * dada2 * mothur * qiime * DECIPHER * vsearch * usearch * emu



Query

You can perform a BLAST like search on the whole PR2 database (not only on the selected taxa).

You can filter the sequences based on similarity level and download these sequences as well as their metadata.
