FieldTrip buffer Python interface

The directory fieldtrip/realtime/src/buffer/python contains a single-file Python module called This provides classes that wrap FieldTrip-style header structures, events, and client connections to a server, including functions for the various requests to read and write samples and events. The module depends on Numpy for representing data matrices and type and value fields of events.

The following Python code example demonstrates how to use the interface:

import sys
import FieldTrip
ftc = FieldTrip.Client()		
ftc.connect('localhost', 1972)    # might throw IOError
H = ftc.getHeader()
if H is None:
    print 'Failed to retrieve header!'
print H
print H.labels
if H.nSamples > 0:
    print 'Trying to read last sample...'
    index = H.nSamples - 1
    D = ftc.getData([index, index])
    print D
if H.nEvents > 0:
    print 'Trying to read (all) events...'
    E = ftc.getEvents()
    for e in E:
        print e
