PEtab is a data format for specifying parameter estimation problems in systems biology. It allows specification of experimental conditions, observables, measurements and information about parameters in tab-separated value files and links these specifications to a model defined in SBML (extensions to other modeling formalisms is currently being developed). More information about PETab is available in the respective documentation.

Users can import PEtab problems using different tools, including AMICI, pyPESTO, d2d, dMod, MEIGO, parPE, pyABC and SBML2Julia. For many of these tools, support is facilitated through the official python library.
