Fig. 11

A view of SARS-CoV-2 MSA with 50 sequences and 29903 columns for different values of \(\alpha\) (see label to the left), from \(\alpha =1\) to \(\alpha =881\) (from top to bottom). Forced vertical blocks (those with the number of columns less or equal to \(\alpha\)) are shown in black. SubMSAs in between vertical blocks (or at the beginning, or the end of the MSA) are in gray. The longest subMSA is shown in light gray. Values of \(\alpha\) correspond to breakpoints shown in  Fig. 10, where the longest subMSA when fixing \(\alpha\) increases in length
