Thank you for the explanation, Vince. Glad Thomas Krahn is assigning
different tags. I wonder will he reassign new tags to the ones with dot
notations?

For SNPs occurring more than once in the tree, they usually have a dot
notation, i.e. L176.1 (below R-M417) and L176.2 (below R-P312).

As of late, Thomas Krahn has taken to assigning each new occurrence of
a parallel mutation a completely different tag, i.e. L199 (original
discovery below R-U106*) and L443 (secondary discovery below R-L2*),
to avoid potential ambiguity inherent in the dot notation. It also
avoids retroactive re-tagging of SNPs.
