v0.1.3

laMEG v0.1.3 — 2025-11-03

🚀 Major New Features

• Automatic scalp surface generation
• convert_legacy_surfaces.py and LayerSurfaceSet now automatically generate and save scalp surfaces (outer_skin.raw.gii, outer_skin.converted.gii) using MNE’s BEM functions.
• Surfaces are correctly converted to scanner RAS coordinates and stored under <SUBJECTS_DIR>/<subject>/bem/.

Improved mesh utilities

• Added _fix_surface_holes() — closes small topological gaps in inflated and other surfaces using VTK’s vtkFillHolesFilter.
• Added get_layer_vertices() and get_interlayer_distance() — utilities for mapping across laminar columns and computing interlayer spacing.

Head surface handling

• Introduced load_head_mesh() for consistent access to scalp, inner skull, and outer skull GIFTI surfaces.
• get_distance_to_scalp() and get_radiality_to_scalp() now rely on load_head_mesh().

Visualization

• Added verify_coregistration() in viz.py to visualize coregistration results interactively in 3D (via k3d).

🧩 Core Improvements

• coregister() now accepts custom scalp, inner-skull, and outer-skull surface filenames.
• Automatically repairs holes in inflated meshes after downsampling.

Post-installation

• Streamlined logging in postinstall.py (removed redundant console prints; unified logging output).

📚 Documentation Updates

• Added clearer post-installation step (lameg-postinstall).

🧾 Miscellaneous

• CI workflow now downloads test data from updated OSF URL (https://osf.io/hbrga/download).
