* Notes and Limitations
- The input trajectory must include =id type element mol x y z= columns.
- The input trajectory must include =id type element xu yu zu mol= columns.
- The P and S atoms of a PS₄³⁻ tetrahedron must have the same molecule ID.
- The cube field is generated from accumulated histogram counts and is
intended for relative spatial-distribution analysis.
- The output file name is generated from the input trajectory name.
The current implementation expects a filename containing =LiI=.
- Large trajectory and cube files may exceed GitHub's 100 MB file-size
limit. Git LFS is recommended for large files.
- The visualization script opens an interactive Mayavi window. A GUI-capable
Python environment is required.
- Before use, confirm that the trajectory format and simulation-cell
definition are compatible with the parser implemented in =dump2cube.py=.
