An option is now provided to use either all ASVs or clustered ASVs on the welcome screen. ASVs are clustered at 100% identity with VSEARCH –id 1.00 See the metaPR2 paper for more information.

It is also possible to use version 1.0 of the database by entering v1 on the welcome screen.

Web application

New Panel: Taxonomy

This new panel provides a table with all the taxa present in the current metaPR2 version with the number of ASV for each species. The table can be easily searched.

Minor changes
  • Information about database is provided on left panel

  • New button to disconnect the application and reloading.

  • Maximum number of samples for Phyloseq: 2000.

  • Taxonomy is constructed from all the samples and not only samples selected.

  • Option to use clustered ASVs in Welcome panel.

  • Barplots. The right side of the graph indicates, for each parameter range, the number of samples that fall into that range as well as the number of samples that contain the taxa selected.
