About
AMICI provides a multi-language (Python, C++, Matlab) interface for the
SUNDIALS solvers
CVODES
(for ordinary differential equations) and
IDAS
(for algebraic differential equations). AMICI allows the user to read
differential equation models specified as SBML
or PySB
and automatically compiles such models into Python modules, C++ libraries or
Matlab .mex
simulation files.
In contrast to the (no longer maintained) sundialsTB Matlab interface, all necessary functions are transformed into native C++ code, which allows for a significantly faster simulation.
Beyond forward integration, the compiled simulation file also allows for forward sensitivity analysis, steady state sensitivity analysis and adjoint sensitivity analysis for likelihood-based output functions.
The interface was designed to provide routines for efficient gradient computation in parameter estimation of biochemical reaction models, but it is also applicable to a wider range of differential equation constrained optimization problems.

Interfaces & workflow
The AMICI workflow starts with importing a model from either
SBML (Matlab, Python), PySB (Python),
or a Matlab definition of the model (Matlab-only). From this input,
all equations for model simulation
are derived symbolically and C++ code is generated. This code is then
compiled into a C++ library, a Python module, or a Matlab .mex
file and
is then used for model simulation.
