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

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?
