[Chimera-users] opening large xyz file

Hello, I'm trying to open a xyz file that contain ~66000 entries (1.7 MB). Chimera hangs and rapidly allocates huge amounts of RAM (more than 60 GB) which is close to limits of my PC, is it normal? Is there any "rescue mode opening" that wouldn't search for bonds to render and/or would show particles as dots or 2D disks instead of ball? My system is spatially small and probably Chimera is trying to search all-to-all particles to render bonds between them, but I do not need this. Is there any way to prevent this behaviour? -- best Michał
