- Line 47: Explain and justify the change to OVERLAP_TOLERANCE by adding a
concise comment next to the variable (OVERLAP_TOLERANCE = 1.2) that states which
metric improved (e.g., reduced spurious atom removals at the GB, better match to
reference atom counts/coordination) and why 1.2 Å was chosen (empirically
minimized difference vs. reference structure). Then add validation after the GB
construction step (the routine that uses OVERLAP_TOLERANCE) that: (a) loads or
defines the reference structure from the manuscript, (b) compares simple metrics
such as total atom count, atom count within the grain-boundary region (atoms
within X Å of the interface), and coordination statistics between the generated
structure and reference, and (c) raises an assertion or prints a clear pass/fail
summary; also add a quick visualization call (e.g., plotting or snapshot) to
show the boundary region for human inspection. Finally, document expected
structural properties (e.g., expected atoms in GB region or expected
coordination defects) in a short comment or markdown cell to make the validation
criteria explicit.

Document the rationale for the OVERLAP_TOLERANCE change and add validation against the reference structure.
The OVERLAP_TOLERANCE parameter was changed to 1.2 Angstroms with the commit message "adjust the tolerance for better result," but this provides no specific justification. Since this parameter controls which atoms are removed at the grain boundary interface and directly affects the resulting structure, the change requires documentation.
The notebook correctly cites the reference manuscript (Qiucheng Li et al., ACS Nano 2015, 9(6), 6308-6315), but there is no visible validation showing that the grain boundary structure matches the expected result (e.g., Figure 2.c from the paper).
Please:
- Add a code comment explaining why 1.2 Angstroms produces better results—what metric improved and why this value was chosen
- Add validation code that compares the generated structure against the reference manuscript, such as checking atom count or visualizing the boundary
- Consider documenting expected structural properties (e.g., number of atoms in the grain boundary region)
