Dear all,

I am trying to visualize a rather large structure (8280 chains with 620 amino acids each) as ribbons in Chimera, starting from a biological unit. I was able to reduce the required memory to something my Linux machine can handle (i7 with 64GB memory) by providing a file with just C-alpha atoms. Chimera successfully displays the copies as surfaces, and also starts to convert all the displayed chains into ribbons (chains as ribbon: finished​), but then becomes unresponsive, runs with 100% CPU usage on one core for several hours and finally crashes. Is this a known problem/limitation and is there some workaround to display such large structures?

Thanks,

Thomas
