On farm, all the SRA sketches are under /group/ctbrowngrp/irber/data/wort-data/wort-sra.

We have a second copy on the temporary quobyte disk per ctb/magsearch#12.

Remote accessibility to the sketches is a work in progress.

Dear branchwater team,

I was wondering if branchwater is intended to be able to accept several genomes as queries. The website allows it but I am noticing that if I select two FastA files as inputs, even though they both seem to load and get green checkmarks, the results in the CSV file are only for one of the genomes in my list (and they are identical to the ones I get if I only select that one genome as query). I am wondering if this feature isn't implemented yet or if it's not intended at all (or maybe I am doing something wrong).

Thanks!
Tanya

After #4 is merged, work on adding dev container so gitpod or github codespaces can serve as development platform (without needing to set up a local docker compose stack)

The accession BK010471 is for a crAssphage that is ubiquitous in human gut metagenomes (link), and in particular is found in the 454 data set SRR073439.

When I do a containment search, I see:

% sourmash search --containment BK010471.fa.sig SRR073439.sig -k 31

selecting specified query k=31
loaded query: BK010471.fa... (k=31, DNA)
--
loaded 3 total signatures from 1 locations.
after selecting signatures compatible with search, 1 remain.

1 matches above threshold 0.080:
similarity   match
----------   -----
 59.0%       SRR073439

and the Venn diagram is pleasing:

However, the FASTA sequence does not have any matches when searched at https://branchwater.jgi.doe.gov/. Any ideas?

thanks!

#4 fixed variable name when normalizing metadata, but we are still missing lat/lon combinations in the values because it is a freeform text field...

(thanks @rchikhi for the suggestion!)

@luizirber not sure where to post this, but don't want it to get lost -

/group/ctbrowngrp/irber/data/wort-data/wort-sra/sigs/ERR1248659.sig is a bad sketch file.

What's the right way to handle this? Can you/we trigger rebuilding it?

Hi

I have tried the web server at https://branchwater.jgi.doe.gov/ many times over the last few days and I have not gotten any results from any of the tries. I did the search using the E. coli K12 genome in fasta format.

After #4 is merged tag a new release and start publishing images, to make it easier to external projects to bring up/expand on branchwater

Questions:

• where to host? dockerhub, quay.io, ghcr.io?

Hello,
Thanks for developing such a great tool. I've been trying to run branchwater on some whole metagenome assemblies that are quite large (0.3G-1G). When I upload even the smaller ones and submit them I don't get any output. I've tried leaving a couple with the tab open for ~12 hours to no avail.
If I leave them for long enough will they eventually complete?
Thanks!
Jenny

Dear Luiz,

Thank you for creating this tool! Can you please tell me how to cite it?

from an e-mail conversation, author luiz:

I'm enjoying the branchwater metagenome query tool. However, are the submitted
queries stored or used within your servers? I want to submit a couple of genomes
that are not published yet, and I want to make sure they are only available
after our manuscript is published.

They are stored only in memory while the search is happening, they are never
stored on disk [0].

I do check the server access logs from time to time to have an idea of how many
unique visitors we have, but this is only data that the HTTP server logs
regularly (time, IP), and doesn't include the HTTP request content (where the
query data actually lives).

Over at sourmash-bio/sourmash#3006 (comment) I mentioned adding extra columns to manifest to hold metadata not available in a signature. I think we can do the same approach to store the SRA metadata into the manifest, and remove the mongodb dependency, returning the metadata from the search index together with the containment.

More refs on the sourmash context: sourmash-bio/sourmash#2180

But... is it a good idea?

Over at #4 I'm trying to make it easy to bring up a new branchwater installation, and there is a bit of a dance for building index, bringing up mongo, loading metadata, and then bringing up server/frontend. Moving the metadata into the index building step makes things easier, but requires to be able to update the manifest in the index in case we want different data (which is not that hard, it's a CSV). It can be more constraining for developing new frontend features, tho?

pinging @bluegenes and @SuzanneFleishman for ideas =]

thanks to @luizirber's nixos setup, we're already logging with caddy

log files on the mastiff server: wc -l /var/log/caddy/access-*

3868 /var/log/caddy/access-branchwater.sourmash.bio.log
23794 /var/log/caddy/access-mastiff.sourmash.bio.log
4511 /var/log/caddy/access-minke.sourmash.bio.log

But we should make this logging visible/accessible/usable.

suggestions from luiz:

• goaccess (https://moth.monster/blog/caddygoaccess/)
• https://www.goatcounter.com/

we could alternatively set up a self-hosted plausible.io if we have issues using the caddy logs...

I'll use this issue to document steps to build a k=31,scaled=1000 index for SRA metagenomes. This is the same process used for the current k=21,scaled=1000 index in branchwater.sourmash.bio, but considering the changes from #4, and bringing new SRA datasets added after the cutoff from the current index (2023-08-17).

Bring up branchwater with {podman,docker}-compose and run a query end-to-end.

Needs #4 to be merged first

TODO:

• add links to FracMinHash paper
• add FAQs like "how do I get the SRA sketches?" and point people at, umm, places. and mastiff.
