The Grid Code Analysis Toolbox - GridCAT
Human fMRI studies examining the putative firing of grid cells (i.e., the grid code) suggest that this cellular mechanism supports not only spatial navigation, but also more abstract cognitive processes. The Matlab-based Grid Code Analysis Toolbox (GridCAT) allows researchers to carry out automated analysis of human grid cell codes in fMRI data. The GridCAT performs all analyses, from estimation and fitting of the grid code in the general linear model, to the generation of grid code metrics and plots. It provides a graphical user interface for researchers less comfortable with programming; researchers confident with programming, however, can edit the open-source code accompanying the GridCAT to implement their own analysis pipelines. An example dataset is provided together with a detailed manual, so that users can explore the GridCAT’s functionality.
The GridCAT is openly available at the Neuroimaging Informatics Tools and Resources Clearinghouse (NITRC). Please download the GridCAT from: http://www.nitrc.org/projects/gridcat
