Example of Krona visualization of blast output for sample 38886230_A.
When using all data for the de novo assembly, and after blast-based filtering of plant contigs, 1266 contigs remained. The majority of these sequences (99%) did not produce a blast hit, but 3 viral blast hits were obtained (left panel). When selecting the viral hits, the blast-based identity is shown (right panel). In this example, one ToBRFV hit and two PepMV hits are obtained. The sequence producing the ToBRFV hit is obtained via a link, which is then further analyzed to determine the presence of the virus in the sample.
