Hi Lu,

You can't restore sessions saved by newer versions of ChimeraX in older versions of ChimeraX. You need to update your ChimeraX in order to restore that session.

Hi, Eric,

Yes, I realized the problem later and solved it already, thank you so much for your comment.

Hi, Eric,

Since you are here answering my question, I would like to make use of this opportunity to ask you a question about making movie, I want to make a movie with five different density maps from cryo-EM with different ligands binding in two different conformation, there is no animation interface in ChimeraX as the same in Chimera, right? It is easier for me to use animation in Chimera to make the movie, but I have all my sessions with colored density map in Chimera, I know I could use commands to make such kind of movie in ChimeraX, but I found it difficult for me. Can you give me some suggestions what should I do? I am sorry that if this bothers you.

Have a nice day!

Best,
Lu
