MPBuilder: A PyMOL Plugin for Building and Refinement of Solubilized Membrane Proteins Against Small Angle X-ray Scattering Data

•SAXS is a unique tool to study MP systems in the native-like environment.•The lack of user-friendly software hinders SAXS data interpretation of MPs.•We present a novel plugin for the widely used molecular visualization system PyMol.•MPBuilder allows to build and refine models against SAXS data.
