[Chimera-users] Running out of memory when recording movies

[Oliver Clarke]

Hello,

I am consistently running out of memory when recording long-ish movies
(using the Animation tool) on a Macbook pro with 16GB RAM. Admittedly there
are a lot of atoms in the model I am using (~120,000), but most are not
displayed (only ribbons).

Chimera is consistently crashing at about the 300 frame mark and looking at
the activity monitor during the recording I can see memory pressure
gradually increasing until Chimera freezes (which is generally not
recoverable).

Is there any way to reduce the amount of memory required for movie
recording? Will deleting all undisplayed atoms help? Is there some way to
perform these operations on disk rather than in memory (most likely a silly
question)?

Cheers,
Oli.
