src/boltz/data/parse/schema.py line 507: chain_type = const.chain_type_ids[entity_type.upper()]. The variable entity_type could be "ligand" in this branch, resulting in a KeyError. This should use the chain.type from the parsed_chain object.

The path for the bfd a3m file uses periods (.) instead of forward slashes (/) as separators, making the path invalid. This assumes the intended path uses the path prefix, similar to the uniref.a3m file.

src/boltz/data/feature/symmetry.py line 274: The line true_coords = best_true_coords.clone() clones best_true_coords, which might not be initialized if the weighted_minimum_rmsd_single function raises an exception. As a result, true_coords could be undefined, leading to errors later. This can be solved by adding a break in the except block in lines 269-271 to prevent the loop to continue after this error.

The variable token_id refers to the loop variable in the previous loop, and its value at this point will be equal to the number of tokens. However, we need all tokens to be present in the one-hot, thus the code should be num_classes=len(data.tokens).
