@arnaudon Does ultraliser
0.4.0 produce reasonable and better results?
I tried on cerebellum, and it looked reasonable with this setup. If I were to decide, I would only use a simple marching cube, I'm not sure about the added value to have sub-voxel resolution here, but I don't know the rest of the algo enough. Are there more test one could do to validate this version? It does not seem tested here. Maybe @asoplata could also try it on his atlas to see? I will keep working on cerebellum atlas in the coming days to better validate, we can keep this open for now, np!

Well, that's already a big sign.

Unfortunately I'm not aware of any, so I'm not sure what we can do.

Ok, that's fine with me. I'm also fine with merging it if you need it.
this will be breaking change, not compat with <4 (at least not with 0.1.0 that was used before). So maybe I can make sure it still works with both? I'm not sure how this will impact the atlas pipeline, etc...
There is no validation for placement hints (AFAIK) so the only way to test the impact on the Atlas pipeline is to try it :) I would first generate the current set of placement hints (isocortex only) with
bbp-atlas --user-config-file customize_pipeline/user_config.json --snakemake-options '--cores 1'
with target_rule: "placement_hints"
in customize_pipeline/user_config.json
, and then install this branch and run
atlas-placement-hints isocortex ...
) but with a different --output-dir
to make sure the new placement hints are "equivalent" to the previous ones,atlas-placement-hints cerebellum ...
If we make a new major release, would it be ok? I'm not sure I can make this work with all the nexus things underneath
I believe I only tested the thalamus placement-hints using the newer ultraliser v0.4.0
, and never successfully used an older version, so it should work - this was my original reason for https://github.com/BlueBrain/atlas-placement-hints/pull/9 .
This also should not affect the current Atlas pipeline, since as Leo said, it only runs the isocortex, and to my knowledge, the isocortex placement-hints algorithm doesn't use ultraliser at all (it uses the "voxel-based" instead of "mesh-based" method).
Ah right, then if somebody can approve, I'll merge this and the #19 and #17 which are on top of this one.
This works with ultraliser==0.4.1, which will appear on spack shortly https://github.com/BlueBrain/spack/commit/567c676fb2d5dd794244e4cf2555244215135fef
