Thanks Elaine, I tried that but unfortunately it didn't help . What is odd to me is that both chimera and chimerax can open mrc/ccp4 files that are substantially larger without too much trouble. Best wishes Hannah On 05/01/2021 19:37, Elaine Meng wrote:
Hi Hannah, I do not know the answer to your question, but suggest trying ChimeraX instead of Chimera. ChimeraX reads the same bild format and is generally much better with large data.

Hi all, I would like to visualize in Chimera the orientations from some angdist.bild files output from relion. I am able to open some .bild files (up to ~5.6MB in size) but I get "not responding" from Chimera when I try to open .bild files ~10-70MB (lots of particles and high angular sampling). I tried on a machine with more RAM but it was the same. Any hints about how to open these or is it just not possible? Best wishes Hannah
