Very excited to present the Great Barrier Reef Microbial Genomes Database (GBR-MGD), a comprehensive DB of 1000s of high-quality prokaryote, virus, plasmid, and chromosome-level eukaryote MAGs using Nanopore long reads. Subthreads incoming. Please share widely. 🙂

Accepted version of our article "Half of microbial eukaryote literature focuses on only twelve human parasites" now out in ISMEJ!

Awesome effort led by undergrad Joanna Lepper and with @hbrappap.bsky.social.

Perfect, thanks Florian! Should have just assumed Anvio would have something. Such a Swiss Army knife these days.

Unfortunately, the power of EnrichM was the consideration of KOs into modules/pathways and doing the stats on the different DBs with standard outputs. Really wish it got published but Joel got an industry job. Maybe one can hack the backend DBs, but my guess is the formats have changed.

Thanks @jcamthrash.bsky.social and @acritschristoph.bsky.social! DRAM I know of, though it's slowwww from what I here--default to single threads for things that could be multi-threaded. Not sure if that's been fixed. There's also Metacerberus for faster annotation.
stevenjrobbins.bsky.social
I think that's why KEGG is so powerful, it ties its genes into machine-readable functional units so you're not looking at them in isolation. My opinion, anyway.
stevenjrobbins.bsky.social
Like here our criteria was that >70% of genes in a an enriched pathway had to be present, including the "key" genes required for proper functioning. One enriched gene says little, but we try to make it as unlikely that we're focusing on statistical accidents.

Yeah, EnrichM just had something like a Bonferoni correction applied to the p-values. And like any gene/based analysis like that, I’d only consider it valid if, say, >50% of genes in a module or pathway were enriched. We don’t come up with big stories based on a single gene.
stevenjrobbins.bsky.social
In EnrichM, you could supply two sets of MAGs, it would annotate with KEGG/PFAM/CAZY, and give outputs showing which KOs and KEGG modules, PFAMS, and CAZY groups were statistically enriched in one set over another, giving a p-value for each KO/PFAM/Module and fold enrichment between the two groups.
stevenjrobbins.bsky.social
Curious, if someone wanted to annotate a large set of MAGs with KEGG, PFAM, CAZY, and then do some statistical comparison, how would you do that these days?

Back in the day I loved EnrichM, but the backend databases for KEGG, etc, are woefully out of date now.

To fill in a bit, the reason I think The Expanse is the GOAT is because it’s got an epic story arc, super interesting world building, but it’s not dense, has great character development. I get exhausted by sci-fi that’s trying to look smart with the sci but don’t have characters I truly care about.
stevenjrobbins.bsky.social
Team, I need a new book/series to read. I’m partial to Sci-Fi or fantasy, points for anything that “changed your life” or got you super reved.

Books/authors I love:
The Expanse series (personal GOAT)
The Bobiverse
Anything Kurt Vonnegut or Neil Gaiman

Already simul-reading 4 non-fiction.

They’re coming y’all…the megaplasmids are coming

(I say this in a slightly frustrated manner as someone who has been thoroughly unsuccessful in getting funding to study megaplasmids for the better part of 15 years)

New pre-print from the Banfield lab, highlighting an interesting case of 1.5Mb megaplasmids found in human gut.

Plasmid genomes were resolved using #PacBio HiFi sequencing with hifiasm-meta for #metagenome assembly. Host association was detected using epigenetic signals.

organizing works 😎

It is the only thing that works in the moment. Admins won't work. Funders won't work. If you're in academia, get involved and support @aaup.org, support your scientific societies, and help them learn to fight and speak out. Collective organizing is the only approach that works.

Automated environmental metagenomics using Oxford nanopore sequencing bmcgenomics.biomedcentral.com/articles/10.... #jcampubs
Automated environmental metagenomics using Oxford nanopore sequencing - BMC Genomics
Background Long-read sequencing has revolutionised metagenomics through improved metagenome assembly, taxonomic classification and functional characterisation. Automation can enhance the throughput, reproducibility, and accuracy of library preparation. However, the validation of automated library preparation protocols remains undetermined for metagenomic workflows, which are particularly sensitive to methodological perturbation. Here, we compare long-read metagenomic sequencing of environmental samples through parallel manual and automated protocols. Results Although automated library preparation led to minor reduction in read and contig lengths, taxonomic classification rate and alpha diversity was slightly higher than manual libraries, including the detection of more rare taxa. Despite this, no significant difference in microbial community structure was identified between manual and automated libraries. Conclusions Despite minor differences in sequencing and classification metrics, automated and manual library preparation resulted in comparable characterization of environmental community metagenomes. These findings demonstrate the suitability of automation for high-throughput long-read metagenomics, with broad applicability to automated long-read sequencing for improved efficiency and reproducibility.

If only 14% of authors don’t care if someone is freely using their data, then contacting automatically attaches strings to using 86% of public data? Is that right?
stevenjrobbins.bsky.social
I don’t have a problem with requiring data to be linked to authors or a manuscript, but it feels…not
wrong, but questionable to require users to contact authors to use public data. Opens up to weird power dynamics w/ data authors, scooping by the authors have a head start with their past data, etc?
stevenjrobbins.bsky.social
And for big studies, seems quite onerous to get 50 labs to agree to let the data to be used.

I have to admit, the idea of being required to contact the owners of all data used makes me nervous. Seems good for the generators, onerous for everyone thereafter?
