Extended Data Fig. 2: Examples of the different groups of sequences identified.

From: The first wave of the COVID-19 epidemic in Spain was associated with early introductions and fast spread of a dominating genetic variant

Extended Data Fig. 2

‘Candidate transmission clusters’ are groups of Spanish sequences that form a clade. ‘Zero distance clusters’ are groups of Spanish sequences that are at zero distance from each other. Finally, the ‘unique’ sequences are Spanish sequences that are more than 1 SNP away from any other Spanish sequence and that do not share a most recent common ancestor (MRCA) node with other Spanish sequences.
