Hi Radhika, Maybe you are using an older version. The current version of the Boltz tool (in ChimeraX 1.11 since July 22, 2025) has an option "Predict ligand binding affinity..." and I do not see that in your image, so maybe there isn't any such prediction in your results. See current help pages: <https://rbvi.ucsf.edu/chimerax/docs/user/tools/boltz.html#dialog> <https://www.rbvi.ucsf.edu/chimerax/data/boltz-apr2025/boltz_help.html> So you may need to get ChimeraX 1.11 and rerun your calculation with the option turned on to get the affinity prediction.

Hello,
I am a Research Scientist at Mount Sinai School of Medicine, NY. I have run Boltz in ChimeraX on a protein-ligand complex, however, I am not able to locate the file for the predicted Kd values. Can you please direct me to the file/location? I am attaching a screenshot of what I see after the run.
Thanks a lot, Radhika <Screenshot 2025-12-04 at 1.52.02 PM.png>
