iShow is a toolbox for Matlab that provides a convenient object-oriented wrapper and other utility functions for use with the Psychophysics toolbox (www.psychtoolbox.org) to run psychophysical experiments. It was written by David Janssen and Patrick Putzky, with contributions from the other members of the Wichmann lab (Neural Information Processing group at the University of Tübingen). The toolbox is intended for internal use only; version 1.0.0 is released here under a 3-clause BSD license to facilitate research reproducibility. Our code calls the toolbox, so to run our code you need this toolbox. We don't offer any support.
