trajectories you can query
A long molecular dynamics run is a tensor of positions over time — but it usually ends up as opaque trajectory files nobody can subset. Earthmover makes the frames, atoms, and replicas you actually want directly addressable.
the data
What we store
Trajectories
Positions, velocities, and forces over time, sliceable by frame, atom, or coordinate.
Ensembles and replicas
Replica-exchange and ensemble runs with replica as an array dimension.
Force fields and parameters
The inputs that produced a run, versioned together with its output.
Derived observables
RMSD, contact maps, and free-energy surfaces, traceable to their source trajectory.
on the platform
What Earthmover adds
-
Subset without re-reading — pull one residue across a million frames in a single query.
-
Simulation-side writes — append frames transactionally while analysis reads the committed state.
-
Reproducible analysis — pin a result to an immutable snapshot of the trajectory.
