The heatmap of ten SARS-CoV-2, one SARS-CoV and six HIV genome

e 7.11 shows the PCA map of the 3-mer word frequency of these

nces, where ten SARS-CoV-2 sequences were represented by S,

RS-CoV was represented by X and six HIV sequences were

ed by H. It can be seen that ten SARS-CoV-2 were clustered and

were clustered into two smaller clusters leaving the SARS-CoV

lier. However, in terms of the distance in this map, the SARS-

a shorter distance with the SARS-CoV-2 cluster compared with

clusters.
