These images are often very large, and so DetectiV offers the ability to subset the data before plotting by using the get.subset function. Figure 3 shows a similar barplot using a subset of the data: only those oligos representing species that belong to the Paramyxoviridae family. It is clear from this image that those oligos representing different groups/species of respiratory syncytial virus have the highest intensity, as we would expect, although there is cross-hybridization with oligos for human metapneumovirus (another paramyxovirus in the same sub-family: Pneumovirinae).
