Dear Chimera Thank you for your support the other day. I also apologize for contacting you outside of business hours due to the time difference. Excuse me, I have a question about the issue of ligand topology for the docking study. ligand: 25-hydroxy cholesterol The topology did not match when I used this ligand for the docking study. Could you tell me how to solve this problem? The thing I tried 1. I tried to add hydrogen atoms on UCSF Chimera by following the URL below, but it did not work Reference: https://www.swissparam.ch/SwissParam_gromacs_tutorial.html 2. I tried to change the conformation of the C23-24 part, but the situation won't be changed. Reference:< https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.h...
