Figure 1From: Genomic variation in macrophage-cultured European porcine reproductive and respiratory syndrome virus Olot/91 revealed using ultra-deep next generation sequencingSchema of the strategy used to analyse the next generation sequencing data. Raw data were quality filtered before being either mapped to a reference genome or assembled de novo. The filtered reads were then mapped back onto the newly constructed genome to search for rare variants from the quasispecies population.Back to article page
