RdRp scan - identifying/detecting viruses- metagenomic workflow- need help

Good afternoon fellow biologists,

I have just discovered the joy of bioinformatics on linux (and its frustrations). However, I don't really understand the workflow for the RdRp scan method to detect viruses. => https://doi.org/10.1093/ve/veac082 => FIGURE 10

For now: I have done a whole genome and small RNA sequencing from a pool of about 600 individuals (RNA extraction and purification). From those reads, I went through all the steps (quality control (trim) / alignment to host (.sam) / samtools (which I may need advice about the flags to select by the way) / SPADES.

Now I feel really stuck. Most of the tools to identify viruses or potential viruses don't work (sometimes can't even be installed) - -BLAST -GeNomad -HMMER

If anyone can help me out with proper examples/ scripts for the RdRp scan method, I would be extremely grateful. Happy to get tips too, on how you would do to detect existing/new viruses.

Best wishes.

Have you tried using conda? Install miniconda3 and you'll be able to install any (well, reasonable) software you need using conda install.

Hello Ram, Thank you for your reply. I have installed conda and mamba, which is even faster. Didn't work i am afraid. Probably because i am on windows linux subsystem I guess.

I think conda is also available for Windows, but I'm not familiar with WSL so my suggestions are not of much value anymore.
