%global _description %{expand:
STEPS is a package for exact stochastic simulation of reaction-diffusion
systems in arbitrarily complex 3D geometries. Our core simulation algorithm is
an implementation of Gillespie's SSA, extended to deal with diffusion of
molecules over the elements of a 3D tetrahedral mesh.

While it was mainly developed for simulating detailed models of neuronal
signaling pathways in dendrites and around synapses, it is a general tool and
can be used for studying any biochemical pathway in which spatial gradients and
morphology are thought to play a role.

STEPS also supports accurate and efficient computational of local membrane
potentials on tetrahedral meshes, with the addition of voltage-gated channels
and currents. Tight integration between the reaction-diffusion calculations and
the tetrahedral mesh potentials allows detailed coupling between molecular
activity and local electrical excitability.

We have implemented STEPS as a set of Python modules, which means STEPS users
can use Python scripts to control all aspects of setting up the model,
generating a mesh, controlling the simulation and generating and analyzing
output. The core computational routines are still implemented as C/C++
extension modules for maximal speed of execution.

STEPS 3.0.0 and above provide early parallel solution for stochastic spatial
reaction-diffusion and electric field simulation.
