Hi Team, I am working with a huge model (and a correspondingly huge map), which makes the handling on my GPU accelerated desktop an agonisingly frustrating experience. In order to speed up simple (rigid-body) fitting of the map and model, I decided to use the -C-alpha trace of the pdb. However, the pdb gets rendered as a bunch of disconnected dots whereas the same pdb in Chimera is rendered correctly with all things. Is this a normal behaviour for ChimeraX? I could use Chimera, but I prefer the way ChiemraX handles large maps as compared to Chimera. In the absence of a quick fix, would there be a way to increase the size of the atoms?
