About the Swedish ASV portal
The portal of Swedish Amplicon Sequence Variants (ASVs) is an interface to sequence-based observations in the Swedish Biodiversity Data Infrastructure (SBDI). In addition to a database of amplicon sequence variants (ASVs) and a web interface, we provide a step-by-step guide(Link opens in a new tab) to submitting raw sequence data to ENA, and a pipeline(Link opens in a new tab) (developed in the nf-core collaboration) for denoising and taxonomic annotation of metabarcoding data.
Why publish data in SBDI?
By publishing your data in the Swedish ASV database and Bioatlas your data will be easily reusable by others and can be seamlessly analysed in conjunction with other datasets in the Bioatlas. The ASVs will be regularly re-annoted as new reference database versions are released; thus your data will be updated with the latest taxonomic information. The ASV database also provides a complement to sequence repositories such as ENA or NCBI that typically only store raw sequencing data. Data in the Bioatlas is further regularly integrated in GBIF and therefor your metabarcoding-based biodiversity data will contribute to global knowledge about biodiversity.
Currently, we support inclusion of ASVs for the 16S rRNA gene for prokaryotes, and the internal transcribed spacer (ITS) for fungi. Later in 2021 we will support the cytochrome c oxidase I (COI) for animals and the 18S rRNA gene for eukaryotes. Other markers can be included on request. Read more about ASV taxonomy in SBDI here.

* To accommodate data from different reference databases, and to facilitate data transfer to the Bioatlas and GBIF platforms, we group GTDB domains and PR2 supergroups together with UNITE and BOLD BIN kingdoms here. Read more about ASV taxonomy in SBDI.
