This is a prototype of a database for sharing genomic data from SARS-CoV-2 wastewater surveillance. Each sample comes with metadata following the PHA4GE wastewater specification and either aligned reads (a BAM file) or SNV frequencies with the sequencing depth per site (a VCF and a TSV file); the prevalence of SARS-CoV-2 lineages is estimated for every sample. The documentation describes what to upload and how samples are processed.
