From: Gauge your phage: benchmarking of bacteriophage identification tools in metagenomic sequencing data
Comparison of viral identification tools on artificial RefSeq contigs. Contigs were generated by randomly fragmenting complete bacterial/archaeal/phage genomes and plasmids deposited in the NCBI Reference Sequence Database (RefSeq) between 1 January 2018 and 2 July 2020, to a uniform distribution. Each tool was then separately run on the true positive (phage genome fragments) and negative (bacterial/archaeal chromosome and plasmid fragments) datasets. For tools which score/probability threshold or categories could be manually adjusted, values/categories were selected based on optimal F1 scores
