LatticeSym

Determine crystal space groups from X-ray diffraction pattern indexing

Scientific AIFree

LatticeSym indexes powder and single-crystal X-ray diffraction patterns to identify Bravais lattice type and space group symmetry. The tool applies systematic absence analysis, Laue class determination, and unit cell refinement to narrow candidates from the 230 space groups. Ambiguous cases receive ranked probability scores derived from intensity statistics and Patterson symmetry analysis.
