Hi MAGgers. I have a question regarding prokka which is taking quite a bit of time to finish. I run the MAG workflow using the coassembly option (all samples as one group) but I realised that DAS refinding output is not carried through to the annotation stage by default so I also flagged. see command below. Prokka is taking long. Is there a way one can speed up the annotation.
Copy code
nextflow run nf-core/mag -r 4.0.0  -profile kaust -resume -c mag.cfg \
	--input samplesheet.csv \
	--outdir results \
	--gtdb_db ./gtdb-tk/release220/ \
	--skip_spades true --skip_concoct true \
	--prokka_compliance_centre NCBI --prokka_with_compliance true \
	--refine_bins_dastool true \
	--binqc_tool checkm2 \
	--coassemble_group true –binning_map_mode all \
	--postbinning_input both

Prokka just takes a long time, there isn't really a way around it, unless you simply skip it. I'm not sure what you mean by DAS_Tool output doesn't go all the way through though?

--postbinning_input both
i meant that the default behaviour doesn’t carry forward the polished bins.
What is your advice for MAG selection? Should one select the polished MAGs or pick the output from one of the tools and proceed. What would be a reasonable thing to do. I am after the proteome. I want to extract the predicted proteome and compare against the metaproteomic data.

Ah, so you mean you cancelled and resumed setting
--postbinning_input both
?

This depends a lot on your specific question, I (persnoally) cannot advise on this sorry

No, I didn’t cancel. The initial job finished default
--postbinning_input
then i resubmitted with
--postbinning_input both
but prokka is taking too long.

I think I will run prokka outside of the workflow because I can split & go

Ah ok
Yeah, sorry about that. Prokka is just a bit too old nowaday, we want to replace it with Bakta but haven't got there yet

Bakta? perhaps I can use bakta myself then 😉

If you're only interested in Bacteria: https://github.com/oschwengers/bakta
It is basically a more modern version of Prokka with a much better database. It;s actually recommended by Torsten (original dev. of Prokka)

nice, thanks for the tip
