analyzePRF is a MATLAB toolbox for fitting population receptive field (pRF) models to fMRI data. It is developed by Kendrick Kay ([email protected]).

The toolbox has several dependencies:

• MATLAB Optimization Toolbox
• GLMdenoise (necessary only if you use the GLMdenoise feature; to download GLMdenoise, see http://kendrickkay.net/GLMdenoise/)

Also, the code makes use of "parfor" (Matlab Parallel Computing Toolbox). However, this is not mandatory, as you can change the "parfor" contained in fitnonlinearmodel.m to a regular "for" loop, if you like.

To use the toolbox, add it to your MATLAB path: addpath(genpath('analyzePRF'));

To try the toolbox on an example dataset, change to the analyzePRF directory and then type: example1; This script will download the example dataset (if it has not already been downloaded) and will run the toolbox on the dataset.
