Dear Dr. Meng, I hope this message finds you well. I am writing to you as we are planning to utilize ChimeraX for structural analysis in our upcoming research projects. As we prepare to integrate ChimeraX into our workflow, we are particularly keen to ensure that our approach and the resulting figures are in line with scientific standards and will be well-received by the academic community. To this end, we would greatly appreciate if you could provide us with any references or examples of published research where ChimeraX has been used for similar purposes. Specifically, we are looking for insights into how figures generated using ChimeraX have been formatted and validated in peer-reviewed publications. We aim to adhere closely to best practices and ensure that our use of ChimeraX enhances the credibility and scientific rigor of our findings. Any guidance, examples, or recommendations you could share would be immensely helpful. Thank you for your time and support. We look forward to your response and any assistance you can provide.

If you mean you already have a structure of a ligand-protein complex (such as from experimentally determined structures or the output of some other protein-ligand docking program), then the answer is yes, you can use ChimeraX to analyze the interactions. For examples of what you could do, see the "protein-ligand binding sites" tutorial: <https://www.rbvi.ucsf.edu/chimerax/docs/user/tutorials/binding-sites.html> See also the ViewDockX tool for looking at results output from other programs that do protein-ligand docking: <https://www.rbvi.ucsf.edu/chimerax/docs/user/tools/viewdockx.html> (2) there is no standard. You have to use your own scientific (and for a paper figure, artistic) judgment, based on what you are trying to show and the details of the proteins you are interested in. I hope this helps, Elaine ----- Elaine C.

Dear Dr. Thomas Goddard,
I hope this message finds you well. I am very thankful for your great tutorial on the UCFS Chimerax YouTube channel.
I have a few questions that need your kind response:
1- Can we apply UCFS Chimerax for detecting the interaction between protein & ligand, or small molecule (from Pubchem library) and protein? 2- What is your standard for increasing or decreasing C-alpha distance (in Angestrom) to color the structure that is different between the Alphafold prediction and the experimental one?
Thank you for reading my message, and I look forward to hearing from you.
