ValueError('Invalid contig string: A')

[fregat17]

Maybe I misunderstood how to set the entire chain in target_dict_cfg, but I was getting an error with just A as chain range selection

Error in call to target 'proteinfoundation.datasets.gen_dataset.GenDataset':
ValueError('Invalid contig string: A')
full_key: generation.dataloader.dataset

target_dict_cfg:
  my_target:
    source: my_targets           # Subfolder in $DATA_PATH/target_data/
    target_filename: my_protein  # PDB filename (without .pdb)
    target_input: A1-150         # Chain and residue range

The target_input field specifies which residues to use:

A1-150 -- Chain A, residues 1-150
A1-100,B1-50 -- Multiple chains/ranges
A -- Entire chain A

When I explicitly set my chain range as A1-392, everything worked.

Can you give please share the full target details you are adding and the commands to reproduce this? The code is set up to always expect a range as the example shows. I can update the readme to remove just A as a valid option
