Accumulation of copy-back viral genomes during respiratory syncytial virus infection is preceded by diversification of the copy-back genome population followed by selection

The goal of the analysis based on this dataset is to understand how non-standard viral genomes of the copy-back type evolve during an infection. We used respiratory syncytial virus (RSV) as a virus model and lung cells (A549) as a cell model (31 samples). Six samples were nasal washes from RSV infected children.
