This service aims at checking which taxa detected and identified from eDNA metabarcoding sequences are listed as NIS and which taxa are not (i.e. native or unrecorded NIS). This service uses available GBIF (Global Biodiversity Information Facility) records of NIS for each Country provided by the Invasive Species Specialist Group (ISSG). it checks if a species is present in the checklist and if this is the case, the species is flagged as being invasive for that country by adding 1 (yes) or 0 (no) to the column isInChecklist of the data frame, and the checklist key or a note to the ref_checklistKey column, for the corresponding cases. It represents the Step 3 of the Metabarcoding Workflow within the Internal Joint Initiative.

This is the output file of Step 1 (Metabarcoding Runner) and the input file of Step 2 (Metabarcoding Syntax Normalizer) for the Metabarcoding workflow. This file is a taxa table containing the number of DNA sequences assigned to each taxon detected using High Throughput Sequencing of environmental DNA samples.
