Software development

  • BIOCHAM (the Biochemical Abstract Machine) is a software environment for modeling, analyzing and synthesizing biochemical reaction networks. BIOCHAM-web allows you to try it on-line through a web service. Beyond making simulations of different kinds, BIOCHAM provides unique features for
    • importing and exporting biochemical reaction networks (CRNs) s in different formalisms and formats,
    • performing various static analyses of CRNs,
    • specifying behaviors in (quantitative) temporal logic,
    • verifying tempoal properties by model-checking, and estimating parameter sensitivity and robustness,
    • searching parameter values under temporal logic constraints.
  • New release: Biocham v4.0 is a complete rewriting of Biocham and its notebook, with new features for
    • influence networks with forces
    • compiling input-output functions into elementary CRNs
    • learning models from data.

  • CellStar image tracker as part of the Yeast Image Toolkit a collective effort for automatic tracking of yeast cells in time-lapse microscopy.

  • FO-CTL is a constraint solver for full First-Order Computation Tree Logic with linear arithmetic over the reals, FO-CTL(ℝlin), in Constrained Transition Systems.

  • ClpZinc a Horn clause front-end for the MiniZInc modelling language for expressing search strategies by constraints

  • MiniZinc-CMAES a stochastic optimization backend for the MiniZinc modelling language
