Dear John (cc to vmd-list),
I enjoyed your recent paper on "Immersive out-of-core visualization of
large-size and long-timescale molecular dynamics trajectories". This is
an issue that we are also struggling with here in the lab, and I wonder
whether there may be a development/beta version of VMD with such
features available for testing.
It's also not clear to me whether this is just an extension (plugin?)
to VMD, or an intrinsically different/separate build.
Thank you very much in advance,
Marc
