Error while running af2_metric.py file

[sssure02]

Hi,

I was trying to reproduce the data using the Tutorial: Hallucinating PD-L1 binder, and I have downloaded the weights using the instructions found in the alphafold repo. After running the af2_metrics.py file, I keep getting this error:

Using model_4
Traceback (most recent call last):
File "/wsu/home/hd/hd18/hd1839/myprog/RFDesign/scripts/af2_metrics.py", line 419, in
main()
File "/wsu/home/hd/hd18/hd1839/myprog/RFDesign/scripts/af2_metrics.py", line 274, in main
Lmax = max([len(s) for s in seqs])
ValueError: max() arg is an empty sequence

Any suggestions for resolving the error? Thanks.
