Memory issues when working with a large trajectory

[vuqv]

Hello,

Thanks for making an awesome MDToolbox for Julia.
I have a question regarding memory problems when I analyze a large DCD file.
My DCD file contains many frames and I want to loop through trajectory to analyze frame-by-frame, it looks like the script load all frames into ram, which makes the computer freeze.

Is it possible to load a certain frame to memory to do some stuff and load the next frame, .. just like MDAnalysis does?
Thanks,
Quyen
