Hello, I am going to attach my command line. OK, so I created a specific capsid that is not all one monomer. It has 3 different monomers in a specific ratio. I have toggled around with different options below to try to save in PDB, the save option from my understanding should be the selected only because this capsid was created using the matchmaker. I tried display only as well just to try to see if that worked. I also have used the relative model from biological assembly of 1LP3 and tried to save or not save options and have kept all consistent with hybrid 36 (default). All these options say "saved", however when i go to open any of them, they do not at all. My objective is to save the whole capsid so when I open it I can perform the density map to measure the volume inside. The weird part of this is when I open these saved creations in Chimera they will open how I want them to, but not in ChimeraX. I am not too sure why. Please help me and I hope everyone is well, have a good night. UCSF ChimeraX version: 1.3.dev202110160902 (2021-10-16) © 2016-2021 Regents of the University of California.
