Subject area	Biology, Genetics and Genomics
More specific subject area	Phylogenetics and Phylogenomics
Type of data	Excel file
How data was acquired	Sequence data were downloaded from GenBank, manually checked and annotated. Analysis were performed using state of art freely available programs for phylogeny, population dynamics and selective pressure analysis.
Data format	Raw, filtered
Experimental factors	PCV2 complete genome sequences were downloaded from Genbank and annotated with the respective collection country and data. Sequences have been aligned and the consistency of the alignment was checked. All sequences were scanned for recombination and subdivided in genotypes or recombinant forms. Databases generated in this way were used for further analysis.
Experimental features	PCV2 sequences download, quality check and annotation.
	Sequence alignment, recombination analysis, Coalescent based analysis of population parameters and reconstruction of viral spreading patterns. Analysis of selective pressure acting on different coding regions.
Data source location	n/a
