Expected Behavior

Successful parsing of 9 mmCIF files.

Current Behavior

Returning error hit.name did not start with PDBID_chain

Steps to Reproduce (for bugs)

Custom import of mmCIF template will always return error no matter how many resets

ColabFold Output (for bugs)

Traceback (most recent call last):

hit_pdb_code, hit_chain_id = _get_pdb_id_and_chain(hit)

raise ValueError(f'hit.name did not start with PDBID_chain: {hit.name}')
ValueError: hit.name did not start with PDBID_chain: AF-P00750-F1-model_v4_A

Context

I've read previous resolved issues and my file comply with the fixes but resetting the runtime will always return the error. I'm not too familiar with PDB and mmCIF files and I interpreted the error as unadded chain name. However I did found label_asym_id and the chain label so I'm quite confused. The file is also an AlphaFold output of tissue-type Plasminogen Activator on UniProt. The file is
tPAmmCIF.zip

Your Environment

The ColabFold notebook with A100 GPU as accelerator.
