for MCF10A also seems to be dependent a lot on density! looks very different compared to this (over)confluent epithelia i imaged some time ago on confocal. +1 for zarr+dask, has been working great for us with on data πŸ‘Œ any tricks on how to convert .czi to .zarr without loosing compression?

In my experience the default zarr already scores quite efficiency on disk, but thats for data that has lots of zeros. In terms of czi conversion i would use the bioio package. However i don't know if you can maintain the compression. Otherwise native zarr supports zipstore, which might help.

Nice! Indeed nuclei are pancakes when they are not inside a 3D matrix, since glass or hard plastic is incredibly charged, pulling all towards the interface. Regarding the big files, i suggest to use zarr and dask, seems like the whole field is moving there.

first data from the new LLSM in PertzLab @olivierpertz.bsky.social! i always thought nuclei were spherical but they are pancakes???? so much more to see in 3d, but data volume produced is insane, we will have to rethink our analysis pipelines. tips welcome! here shown in @napari.org

Have you ever thought about inflating tissues?
Or maybe quickly deflating those inflated tissues?

An eppendorf centrifuge in that specific nicotine-yellow color from the 80s. It's the exact color as the old fridge in your garage that you keep sodas in that your parents replaced in 1997, and which has outlived a half-dozen of its replacements.

"Why don't you buy a new centrifuge"

Because everyone knows that any appliances in that shade of yellow will outlive you and your entire family, look at it
