  The formalism proposed in Phys. Rev. Lett. 116, 078001 (2016) for
determination of the normal and tangential inter-particle forces in frictional
disks from visual data was criticized in a comment to that paper. However the
theory developed in the original publication is aimed at finding the forces
when provided with accurate measurements while the comment addresses a
different problem, being the statistics of forces in a configuration with
uncertainty of the relevant parameters. We address this difference in
perspectives and point out that even with experimental errors one can improve
the results using an iterative procedure proposed in Phys. Rev. E. Rapid
Communication, 93, 060601(R) (2016).
