Dear Chimera users, I have been recently transferring to ChimeraX from the conventional Chimera and I am currently struggling with two features existing in Chimera but not in ChimeraX. 1. How could I combine two or several different ChimeraX files? I have been doing in Chimera as I was opening new chimera files by "Files...Open...", this is a window pop-up as the following and if I click "No", the new Chimera will be added to the cold Chimera as the old one was not closed. However, when I performed the similar operation in ChimeraX, there is no such window and the new ChimeraX would REPLACE the old one. I wonder if there is a way (probably using command to open? but I did not find the correct open options.) to open the new ChimeraX without closing the old one? [cid:23bcde4a-3b02-4fc4-9b5e-7b034cd22a9f] 1. I am also working with tomogram slices and cellular segmentation. Previously, in Chimera I can set this Transparency value to 0 and the Plane of the tomogram will be totally opaque. Now in ChimeraX I have used the command "transparency #2 0" (#2 is the tomogram files) but it still look quite different from my previous images in Chimera. Is there a way to set it up in ChimeraX so it could look similar as before? [cid:1e2eb72a-f2e5-4c83-b4e4-81b881b9dc67] Thanks again and I am very grateful if any advice or help could be provided.
