2.0.0

Date

March 2026

Provides FIFF read helpers that walk the FIFFB_MNE_SOURCE_SPACE blocks (extracting FIFF_MNE_SOURCE_SPACE_POINTS, _NORMALS, _TRIANGLES, _SELECTION and the neighbour tables), plus decimation, patch-info loading and basic geometric utilities (vertex area, nearest neighbour). All routines are designed to behave identically to the read_source_spaces function in the MNE-Python source.
