This is a Mathematica package for analyzing retinotopic mapping data collected in the classical method: handmapped receptive fields drawn on a spherical screen. The package performs basic geometrical calculations based on spherical coordinates, and allows the researchers to explore the dataset easily. My colleagues and I have used this package to generate figures in a number of publications.

The stylistic elements in Topy is flexity. You can visualize your data in many different ways:

1. Move the Topy to a place that Mathematica can find, such as ~/Library/Mathematica/Applications
2. Consult one of the scripts in demo/.
