v1.0.0 — classified volumes + tissue priors

Generated tissue classification and probabilistic priors derived from the
Allen Human Reference Atlas - 3D, 2020 (ontology StructureGraph 16), with
non-brain CSF sourced from a SynthStrip mask of the MNI ICBM152 2009b T1.

All assets are produced reproducibly by generate_all.sh (see README). They
are attached here because the repo gitignores generated/large files.

Contents:

• classify.nii.gz - primary 9-class tissue segmentation (uint8, 0.5mm, values 0-8)
• classify_volumes.tar.gz - 9-class + 4-class + 3-class + cbmerge segmentations
• lookup_tables.tar.gz - all id->tissue LUTs + scheme map.csv definitions
• priors_9class.tar.gz - prior01..08 (float32 0-1, 2mm FWHM, Atropos-ready)
• priors_coarse.tar.gz - priors for the 4-class / 3-class / cbmerge schemes

Priors: 2 mm FWHM Gaussian (DiscreteGaussian), per-voxel normalized to sum 1.
Atropos usage: -p prior%02d.nii.gz -k 8 (or prior__%02d.nii.gz for coarse).
