Re: Protein-ligand interactions
Hello Ahmed, I am not aware of any formal standard for figures, at least in my field, beyond the specific technical requirements of different journals (certain preferred image formats with a certain minimal resolution in DPI, etc.). In practice, the reviewers will complain if they find the figures confusing. So the best you can do initially is to use your judgment as to whether the figures show what you want to communicate. It is often very enlightening to run the figures past colleagues who were not involved in the project and see what their first reaction is (do they immediately get what you are trying to show? do they get confused? can they suggest ways to clarify the figures?). Then once you get feedback from reviewers, what needs to be changed typically becomes clear. Regarding aesthetics, pretty much anything goes as long as it doesn’t confuse the message the figure is meant to communicate. In certain fields, there are conventional color codes that have been in use for a long time, and it often facilitates communication with this research community to follow their conventions (even though nobody can force you to do it; a reviewer could suggest it but I believe it would be wrong for them to make it a strict requirement). But this is never advertised anywhere, you need to find out by reading the literature of this specific field. It is always good if figures are reproducible, and I like using ChimeraX’s command scripts for that (see some examples from my own work here: https://github.com/Guillawme/chimerax-viz ).

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.

Hello Gaullier, I appreciate your detailed explanation and precious advice. ChimeraX is a potential program with various applications with high convenience. We are trying out best to utilize it for our research and trying our best to prepare a robust research article with that. Again, thank you for time and help.
