afniRTI

AFNI Real-Time Interface in Python

Python scripts and modules to enable communication with AFNI's real-time data interface to facilitate neuro-feedback experiments

This project contains both code to communicate with AFNI's real-time interface via network, and example code to do simple processing and stimulus generation, based on the received data.

The code within this package has been derived from python modules in the AFNI software suite, which were repackaged and modularized to improve portability.

The communication is handled by the afniRTI module, and the shipping demonstration experiment is implemented using PsychoPy.

The experiment can be run by PsychoPy running on Windows, Mac OS X, and Linux - with AFNI running on a Linux or OS X computer sending the data (via TCP) to the computer running the experiment in PschoPy.

Stimulus initialization and experimental setup is done in the 'setupExperiment' routine, processing and modeling of AFNI data is done in the 'compute_TR_data' routine, and updating of stimuli to deliver feedback is done by the 'runExperiment' module.
