SARS-CoV-2 genomes are collected from various open source genomic banks. A set of SARS-CoV-2 genomes are selected for visualization under both the A3 and C1 modules of the metagenomic analysis system MAS. Multiple probability measures are mapped as relevant 1D histograms, and it is convenient to observe distinct differences among various distributions to organize similar patterns into relevant groups. Sample genomes were processed, and their visual results were illustrated.
