SIAN: software for structural identifiability analysis of ODE models
For researchers modeling biological processes with ODEs, SIAN enables a priori checking of parameter uniqueness, addressing a bottleneck in model analysis.
SIAN is a new software for structural identifiability analysis of ODE models that can handle problems previously intractable by existing packages.
Biological processes are often modeled by ordinary differential equations with unknown parameters. The unknown parameters are usually estimated from experimental data. In some cases, due to the structure of the model, this estimation problem does not have a unique solution even in the case of continuous noise-free data. It is therefore desirable to check the uniqueness a priori before carrying out actual experiments. We present a new software SIAN (Structural Identifiability ANalyser) that does this. Our software can tackle problems that could not be tackled by previously developed packages.
