In ChimeraX you have to use the "combine" command to make a new model, and then save the new model. There is no GUI for combining yet. After combining, then you can use either the "save" command or menu: File... Save to save the new model.
My example used commands for both steps: https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2021-December/003032.html

Hi Kenji, I don't really know how to use Pymol very well, so I can't help with that program.
However, my only guess is that in ChimeraX, you did not correctly combine the receptor and ligand models into one model before saving it as a PDB file, or that when you saved you didn't save the combined model but some other model.
I happened to have an extremely old version of Pymol on my old computer (it does not run on my current computer), and when I opened result10.pdb saved from your session with exactly the commands I sent you earlier, I could see that the ligand was displayed, see screenshot:

The reply I sent before with the exact commands that I used to make the file is here: https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2021-December/003032.html
...and I also attach that file, result10.pdb: <result10.pdb>
I hope this helps, Elaine

Dear ChimeraX
Thank you very much for your kind words in the past. When I opened the PDB file and mol2 file saved by pymol using the method you gave me, the ligands disappeared.
How can I get pymol to display the ligands as well?
Here is in detail.
As you suggested, I created a new model by combining #1 and #10, and saved the newly single model in a PDB file. However, when I displayed this file in pymol, I could not see the ligand as shown in the figure. <image.png> <image.png> So we tried to align the ligand OSW-1 to the protein osh4 in this figure, but it was difficult to analyze because OSW-1 was far away from the distance of the protein osh4 as shown in the figure below.

Also, I've looked at tutorials and other sites on the Internet to try to figure out what's causing this, but no luck!
I'm sorry for the many questions.
