#RELION
Since last year, I've been making a RELION GUI that supports viewing, navigating and running jobs in a way completely compatible with the original RELION pipeline. Now it's working nicely for both SPA and tomography! Please try it out - github.com/hanjinliu/hi...

Initial attempt at replicating in relion (parameters in next post). This is for Aca2-RNA, using a 100k subset of the 2D-classified particles (no prior 3D cleanup).

A 1-class ab initio in relion, then local refinement in relion (1.8deg searches+blush) gives a nominally 3.3Å map; 3.5 Å w/out blush.

Oh wow, this is 🤯 amazing: ~3-fold acceleration of running #relion on A100 GPUs for realistic single-particle refinement by the group of Guangwen Yang at @tsinghuauniversity.bsky.social
.

What a fantastic example of #OpenSoftwareAcceleratesScience, literally! 😍

We're excited to announce the beta-release of #RELION-5.1! 🥳 This release has important updates on our #amyloid processing pipeline, as described in this preprint: doi.org/10.64898/202... There are also some tweaks for #teamtomo.

Cryosparc isn't the only tool you should RELION 🥲 #cryoEM
To open cryoSPARC all I have to do is type “cry” into the search bar and it comes up. Feels about right. #cryoEM

If it helps anyone receiving a rejection today: my original paper on #RELION was rejected by @pnas.org and Structure @cellpressnews.bsky.social. The method still did pretty well.
Sometimes you just have to persevere through negative reviews. Reviewers, please be kind :) #methodsmatter bit.ly/gs2-scholar

1/5: Over the last few months, I have been working on an update for the #FollowRelionGracefully dashboard, which offers improved real-time job previews for #cryoEM #Relion jobs.

At some point, Doppio will replace relion's gui. Already you can do more in Doppio than in relion! 🤩

You can download RELION-5.1 from github.com/3dem/relion (branch ver5.1)

Note that the beautiful startup image of dynein:dynactin on a microtubule was provided by Sami Chabaan from the @carter-lab.bsky.social. 🤗

The reason why this site is dying isnt metrics or pile on culture, its because of people like me, in their 40s, making references to pre-Atlantic records era Bad Relion

We are looking for a computational postdoc to work with us on new optimisation algorithms to make #RELION even better. Join our bubbly team at the @mrclmb.bsky.social in Cambridge, UK. 🤗 RTs appreciated.

It's a small project, but hopefully useful for others running RELION jobs.

Just for fun, reprocessed a subset (1200 mics) of EMPIAR-11918 (beautiful 40kDa RNA-protein complex) with cryoSPARC to compare with BLUSH/RELION workflow - 3Å NU-refine from 60k blob-picked particles after quick classification without alignments

Using github.com/hanjinliu/hi... installed in native Windows to run RELION installed in WSL -- as if you are running RELION in Windows!

Just installed and twiddled a few knobs, but I am already impressed with `himena relion`. Amazing job @liu-hanjin.bsky.social! Would be great if this could be made into a default interface for relion.

I've just released a small open-source utility for RELION users: relion_tracker.
RELION stores a lot of useful information in the *_optimiser.star files, but I often found myself repeatedly grepping STAR files to see how metrics were changing across iterations.
