AssertionError: Source atom array must be provided for symmetric motifs

[zqx-yang]

I would like to generate some unconditional symmetric oligomers with an input as such:

{
    "c5-base": {
        "dialect": 2,
        "length": 100,
        "is_non_loopy": true,
        "symmetry": {
            "id": "C5"
        }
    }
}

and

inference_sampler.kind="symmetry"
diffusion_batch_size=1
low_memory_mode=True

but I kept getting AssertionError: Source atom array must be provided for symmetric motifs.

The same goes when using the examples of unconditional multimeric design provided in symmetry.md.

May I ask if the input should be modified somehow? Thanks in advance!

I will let Aiko comment on the technical side here but an easy workaround should be to supply an empty / random pdb as input

Thanks for the suggestion!

However, supplying an empty pdb gives TypeError: Use () not None as shape arguments, while a random pdb gives

ValidationError: 1 validation error for DesignInputSpecification
