Could you build this?
No Computing RMSD_n crystal-packing similarity for molecular crystals requires specialized crystallographic domain knowledge, 3D symmetry group handling, and advanced scientific computational algorithms.
What it would actually take: Building OXtalign requires deep expertise in crystallography, spatial geometry, and cheminformatics. The software uses C++ or Python (with libraries like SciPy, NumPy, and spglib) to handle crystallographic information files (.CIF), generate 15-molecule coordination clusters across space groups, and solve non-trivial point-cloud alignment and permutation problems to calculate invariant RMSD metrics efficiently.
