Igneous, our Python software for managing Neuroglancer 3D images, meshes, and skeletons, is now published open access in Frontiers in Neural Circuits!. Aleksandar Zlateski @jalex_bae @tartavull @nkemnitz1 @jingpeng_wu @SebastianSeung.

xs3d 1.8.0 . - ~5-15% faster cross sectional area calculation.- xs3d.slice accepts C order arrays at full speed.- xs3d.slice has a physical distance crop operator.

fastremap 1.17.0. - Adds typing, thanks MattTheCuber!.

Thanks MattTheCuber!.

fill_voids 2.1.0. - Adds type annotations.

connected-components-3d 3.24.0. - Adds type annotations. Thanks to MattTheCuber!.

Kimimaro 5.3.0. - Adds step parameter for sparsely evaluating cross sectional area.- Fixes errors in CLI.- Fixes error in postprocess .- Changes default PDRF exponent 4 -> 8 for smoother skeletons.

CloudFiles 5.3.2. - Fix (hopefully for good!) the multiprocess hanging bug. Use as many processes as you want without fear.

igneous-pipeline 4.29.0. - Adds floating point support for ccl thresholds.- Adds igneous skeleton convert command for creating SWCs . e.g. igneous skeleton convert gs://example/ ./output/ 1,2,3,4,5. Generates swc files 1 thru 5 like ./output/1.swc.

CloudVolume 12.3.1. - Fix for zarr2 viewing with "igneous view . ".

RT @19joho: I was turned away at my pharmacy today from getting a Covid vaccine. Even though I was willing to risk a sore shoulder @DrMaka….

CloudVolume 12.3.0 . - Basic support for zarr3 images up to 5 dimensions with OME-Zarr support for versions 0.4 and 0.5. Could still be buggy! Open an issue if you run into trouble.

check the link for an example making all of these objects from scratch.

Did you know microviewer can also display objects using vtk? Good for experimenting.

Kimimaro 5.2.0. - Vastly faster join_close_components.- Optional dependency on pykdtree further increases speed.

microviewer 1.13.0 . - vtk based viewer visualizes skeletons with radius and cross sectional area.

cloudfiles 5.2.0. - Supports the |FORMAT: suffix style Neuroglancer has adopted.

kimimaro 5.1.0. - Big performance increase in postprocessing specifically in loop removal.

igneous-pipeline 4.28.3. - fixes bug in whole dataset CCL.
