Prodigy input error

I’m having some problem in the analysis of some protein (chain A)- protein (chain C) complex, because even if I’m not selecting it, it sees some nucleic acid (chain B of my complex) and report this error. how can I avoid this? I never had this problem before with this software.

PS: I tried also prodigy crystal but I didn’t have any improvements

thanks in advance

We have implemented more strict validation. But in this case since you don’t use chain B this error should ideally not appear.

For now simply delete chain B from your PDB (until we fixed the issue)
