I have got some viral genomes (using MARVEL) isolated from metagenomics data. I am wondering what programs I can use for functional annotation and taxonomic classifcation for the viral genomes?
I have used PROKKA (specified --kingdom viruses) and eggnogmapper for annotation but I am sure there are programs out there that specifically works on viruses.
Viruses are super diverse and range hugely in size and the number of genes. Tools that I have found useful for annotation of viruses are RATT, VaPiD and VGas. Each has pros and cons. I would maybe suggest starting with VAPiD but then I am not too sure what your data is like, specifically how novel your virus is.
There are few tools for virus annotation in that list https://github.com/NBISweden/GAAS/blob/master/annotation/knowledge/annotation_tools_genome.md
Thank you for your suggestion!
