The COVID-19 Genotyping Tool user interface

There are three main tabs: Input, which allow users to upload SARS-CoV-2 genome sequences and adjust the visualisations; Details, which allows users to view details of the analysis algorithms; and Data, which allows users to view data sources and privacy information. The main panel consists of a tab interface with the three visualisations in the application (UMAP, MST, and SNP). Metadata corresponding to the region of sample origin, the country of sample origin, and the sample collection date can be toggled and overlaid on each visualisation. MST=minimum spanning trees. SARS-CoV-2=severe acute respiratory syndrome coronavirus 2. SNP=single-nucleotide polymorphisms. UMAP=uniform manifold projection and approximation.
