protein-molecule contact log issue

[mrodriguez.81@…]

Good afternoon.

To whom it may concern.

I am attempting to identify the residues with which a compound (A) is
interacting with a target protein (B). I opened both pdb files in ChimeraX,
I selected the compound and did as follows: Tools > Structure Analysis >
Contacts (selected output info to log).
The results which I get are the contacts inside the same protein (prot(B)
with prot(B)), instead of compound(A) with protein(B).
I have tried selecting only the target protein, selecting both, creating a
new pdb file with the comp and the compound together, but nothing works, I
still can not get to know which residues from the compound are contacting
my target prot.

How could I solve this?

Thank you

Best,
Mario
