Hi all, I’m very happy to share my new preprint on laminar MEG using high-precision forward models and OPMs: biorxiv.org/content/10.1101/20!

It features comprehensive simulations of OPM-MEG arrays with varying sensor counts, measurement axes, sensor-scalp offsets, and SNRs and aims to provide guidelines on how to successfully infer the laminar origin of cortical sources with OPMs.

bioRxivInferring laminar origins of MEG signals with optically pumped magnetometers (OPMs): a simulation studyWe explore the potential of optically-pumped magnetometers (OPMs) to infer the laminar origins of neural activity non-invasively. OPM sensors can be positioned closer to the scalp than conventional cryogenic MEG sensors, opening an avenue to higher spatial resolution when combined with high-precision forward modelling. By simulating the forward model projection of single dipole sources onto OPM sensor arrays with varying sensor densities and measurement axes, and employing sparse source reconstruction approaches, we find that laminar inference with OPM arrays is possible at relatively low sensor counts at moderate to high signal-to-noise ratios (SNR). We observe improvements in laminar inference with increasing spatial sampling densities and number of measurement axes. Surprisingly, moving sensors closer to the scalp is less advantageous than anticipated - and even detrimental at high SNRs. Biases towards both the superficial and deep surfaces at very low SNRs and a notable bias towards the deep surface when combining empirical Bayesian beamformer (EBB) source reconstruction with a whole-brain analysis pose further challenges. Adequate SNR through appropriate trial numbers and shielding, as well as precise co-registration, is crucial for reliable laminar inference with OPMs. ### Competing Interest Statement The authors have declared no competing interest.

describes itself as a fast, lightweight, and modular Continuous Integration service for Linux.

The official overlay now makes the latest 1.3 release available for the wider community.

See my post for links: blog.ferki.it/2023/07/25/gento

I contributed the ebuild earlier, but my above post remained in a draft status – now I finally published that too!

Setting up Laminar might be a good weekend project, if you want to give it a try :)

Happy hacking!

@marianom @skye With CI that allows you to build arbitrary jobs based on client-sent triggers for activation (like git hooks or fossil's own equivalent) or even cronjobs, it would be quite feasible to get good results with something like #Laminar (laminar.ohwg.net/) or #ConcourseCI.

I am now a GURU contributor \o/

GURU is an official package repository maintained collaboratively by users: wiki.gentoo.org/wiki/Project:G

I maintain several unofficial packages in my overlay, like , , , , , , .

@icedquinn@blob.cat The bare essentials are up and running, but the cmake part seems to want to download javascript sources for the frontend, so a sandboxed ebuild is a no go for now. Other than that, it seems to be running fine, its simplicity in run jobs is also pretty neat, as I like #Bash over #YAML for this kind of stuff.

One potential downside I encountered was the inability to sort jobs into directories, but at this stage that's not a problem at all. Might also be easily fixed. Persistent workspaces might be something I could be interested in later down the line, for now it's fine. Pulls are done from a local repository anyway, and I can add
--depth=1 if needed as well.

So far, I think
#Laminar might be the best option I've encountered thus far!

@icedquinn@blob.cat #Concourse was quite the mess to try and set up, I eventually just didn't finish up with it.

#Laminar actually looks good, and I do very much enjoy simplicity. Looks like I can schedule runs through a single line in a git hook as well, which is exactly the kind of minimalism I want. Most CI systems seem to depend on GitHub, GitLab, or Gitea webhooks, and I don't want to use any of those since cgit Just Works.

It
seems much simpler to set up than #KrakenCI, so perhaps I'll try that one first!

@DrHyde Oh, I think I know that feeling; my sympathies.

I am much happier with using for my personal needs on a home server.

I usually describe it as a DIY CI: it allows one to build the CI solution they need, instead of fitting their needs to their CI solution.

Sure, it is a different kind of tinkering, but I thought it might be of interest for you too.
