Thanks Uri (for both the complement and being rigorous in your benchmarking)!

This is suuuuper cool! Quantitative modelling of structures in fluorescence microscopy images across several orders of magnitude 👀

This is the result of a super fun collaboration with Andrew Gunawan from @locusj.bsky.social and Erik Meijering's groups at UNSW (there aren't many collaborators I'd brave a 9-11 hour time difference for, but these guys are great 🦘) and @micoxscopy.bsky.social a bit closer to home! (5/5)

For giggles, we also discovered that you can deliberately force images to be structurally wacky while still getting high scores on quality metrics (please don't try this at home) (4/5)

Most alarmingly, it turns out that sometimes these metrics tell you that your image has got better after image processing, even when your downstream biological analysis gets worse as a result ☹️ (3/5)

We show that PSNR and SSIM fundamentally suck (technical scientific term there) for fluorescence microscopy in general. They also love processed images - even if those processed images don't look all that great. (2/5)

Had a great time teaching on #SOMC25, including my first ever field trip and resultant microscope-based exposure therapy to try and cure myself of my irrational crustacean phobia

Haha definitely! Also I'm not sure how hot Great Uncle Donald's Russian was 😂 I do enjoy the apparent mismatch of energies though

I love everything about this relic I just found at my parents' house. My great uncle Donald met Valentina Tereshkova! Look how happy he is! Look how unimpressed she is with Concorde when she has been into been into actual literal space! Look how mansplainy the caption is!

London microscopy folk - does anyone have an old-school SIM (rather than an iSIM/Sora/Airyscan) that we could have a look at some expanded samples on? Our STED is dead (which rhymes but is also sad) so we're hunting for another system 👀

Okay this worked!!!! I now have a .zarr that I can open in BigDataViewer, which is the biggest achievement in the last two hours/half a packet of biscuits. Thank you! 💕

👋 all aboard the struggle bus! 🚌 (a) was the first thing we tried, (b) I don't understand what this means (I am an idiot who mainly only understands tiff files), (c) I'm in the middle of composing a image.sc post so I'll see you over there 🫡

I have tried 😀 I have failed 😩 This threw an error for our test image (18215x18215 pixels, 3 channels) - I tried massaging the chunk size with no joy. Happy to share the error if it's helpful, but I'm 99% sure that the problem is that I am an idiot and failing to understand something fundamental

This is our first ever attempt to use zarr and the one image we have converted from .nd2 to .zarr as a test seems to have had the effect of opening a portal to actual hell 😂
