A processed version of a mutation-annotated tree from open SARS-CoV-2 genomic data, originally compiled by UCSC researchers at https://hgwdev.gi.ucsc.edu/~angie/UShER_SARS-CoV-2/. This is used as input to an open-data version of the analysis in A molnupiravir-associated mutational signature in global SARS-CoV-2 genomes.
