Hello. When running your ab model weights on an input CSV containing a uid column as well as both heavy and light chain sequence columns, it appears as though your code produced PDB files containing only a single unique PDB chain ID (i.e., A). If the predicted PDB does in fact contain both heavy and light chain structures in it (as a single complex), is it possibly to distinguish the heavy chain structure from the light chain structure within the same PDB file by e.g., giving the heavy chain a chain ID of A and the light chain a chain ID of B?
