Ampseer examines reads in fastq format and identifies which multiplex PCR primer set was used to generate the SARS-CoV-2 sequencing library they are read from. It is intended to differentiate between ARTIC v3, ARTIC v4, ARTIC v4.1, VarSkip 1a, VarSkip 2, Midnight and VarSkip Long primer sets sequenced by Illumina or ONT.
compare key between similarly scored sets, use only complementary keys to differentiate
