Potential unit issue with StructureMatcher.get_rms_dist() in evaluation

https://github.com/facebookresearch/all-atom-diffusion-transformer/blob/b9ce505f170597a7c8ca50d13ce8e15df21cf8c9/src/eval/crystal_reconstruction.py#L98C13-L98C79

This method might return a volume-normalized dimensionless value rather than actual distances in Ångstroms. The normalization seems to be (volume/nsites)^(1/3).

However, in your paper, it appears to treat these values as Ångstrom units.

Could you clarify this, thank you!

Start at src/eval/crystal_reconstruction.py around line 98 and inspect how StructureMatcher.get_rms_dist() is used in evaluation. Check the method's documented units and the apparent (volume/nsites)^(1/3) normalization, then compare the result with the paper's stated Ångstrom interpretation; done means the unit question is resolved and the evaluation is documented or corrected accordingly.
