Any suggestion on metagenomics pipelines for processing shotgun metagenomics whole genome sequencing samples?

Hi, I have some shotgun metagenomics gonorrhea samples and I want to use metagenomics pipeline to process the samples and then detect antimicrobial resistance. I looked into few pipelines so far for metagenomics data such as ATLAS, Sunbeam, MetaSUB/CAP2 and nf-core/mag. They have different steps of data processing with different features and tools used.

1. Is there a review paper or some documents that compares these pipelines in terms of pros/cons?
2. Is there any other pipeline(s) that based on your experience, I can use? or even any pipeline that you think works better among the ones I mentioned?

Any suggestions will be appreciated.

Thanks

The ultimate choice on which pipeline is better depends on your needs. For example, since I am mostly interested in MAGs I use metaWRAP because it has a module called Bin_refinement which produce a final bin set from the output of three different binning algorithms. Of the pipelines you mentioned I would avoid the following:

• nf-core/mag: it use only one binning algorithm (metaBAT2).
• MetaSUB/CAP2: the assembly module consist only in one assembler, metaSPADES which is computationally more expensive when compared megahit
• Sunbeam: I would not pick this one only because it does not have a binning module. However, if you do not care about MAGs and are interested only in antimicrobial resistance genes then Sunbeam would work just fine

The points you mentioned are important to consider and I haven't thought about them. Thank you so much for pointing these out. very helpful!

Not aware of any paper comparing different workflows, but I will add one more to your list and suggest Anvi'o (publication: https://www.nature.com/articles/s41564-020-00834-3). I've been using it to assemble MAGs and have found the tutorials and documentation very approachable. They also have good support and an active community.

Thanks for the suggestion. I just looked at the paper and it seems a lot of works were put on it. I like that it is also powered by Snakemake. Thanks!
