Recon is a python module for (pRF-based) stimulus reconstruction analyses from fMRI data. The main functions include:

• simple reverse retinotopy with the summation method (Thirion et al. 2006; Kok & de Lange 2014; Ekman, Kok & de Lange 2017)
• advanced reverse retinotopy with the multivariate method (Ekman, Roelfsema & de Lange (in prep))
• spatio-temporal reconstruction (Ekman, Kok & de Lange 2017)

$ python

>>> import matplotlib.pyplot as plt
>>> import recon as re
>>> # load prf properties
>>> x0, y0, s0, r2, betas = re.example_prf_data()
>>> # reconstruct stimulus
>>> S = re.stimulus_reconstruction(x0, y0, s0, betas, method='summation')
>>> plt.imshow(S)

Currently this is only available through GitHub and source installation

pip install git+https://github.com/mekman/recon.git --upgrade

or

git clone [email protected]:mekman/recon.git
cd recon
python setup.py install

You also need to install the mansfield module.
