%description
SPHARM-PDM is a set of command-line tools for spherical-harmonic-based shape
analysis. It computes correspondent point-based shape models (PDMs) from
binary segmentations by parameterising the surface with spherical harmonics
and sampling a corresponding icosahedral mesh, enabling group statistical
shape analysis of brain structures and other objects. Part of the NIRAL /
SlicerSALT shape-analysis ecosystem.

This build uses the system ITK, VTK and SlicerExecutionModel (no superbuild).

* Mon Jun 15 2026 Morgan Hough <morgan.hough@gmail.com> - 2.0.0-0.1.20251104git6565932
- Initial package: SPHARM-PDM spherical-harmonic shape-analysis CLI tools
  (master snapshot 6565932). Built against system ITK/VTK/SlicerExecutionModel
  with the superbuild disabled (Fedora no-superbuild policy). Complements the
  FSL FIRST mesh shape-analysis workflow.
