ResIPy (new name for pyR2) is a python wrapper around R2 code family that provides an API and a standalone graphical user interface (GUI) for geophysical DC/IP inversion. ResIPy aims to be both (1) simple and intuitive to use (you can invert your data in one-click with all default settings) (2) but still allowing the user to have full control on data filtering, error modelling, mesh parameters and inversion settings ResIPy is an open-source project, everyone is welcome to contribute.
