inquiry on result intepretation

Open LanSabb opened this issue 9 months ago • 1 comments

Hi

Genomad produces my test-run result

I am likely to deem the contigs as viral sequences if virus_score > 0.95, however most of the results were fully lacked of viral marker genes in the absence of terminal repeats (Note that input is metagenome contigs)

So am I supposed deem them as virus or not ??

Thanks

Unfortunately, it's not straightforward. These can be sequences with genes that are enriched in viruses, but this doesn't necessarily mean that they are viruses.

Have you taken a look at the <prefix>_genes.tsv file to check which annotations you find? Can you share the genes of these sequences?
