FieldTrip buffer Python interface
Client side pure Python implementation
The directory ‘‘fieldtrip/realtime/src/buffer/python’’ contains a single-file Python module called ‘‘FieldTrip.py’’. 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 interfac
:::python import sys import FieldTrip ftc = FieldTrip.Client() ftc.connect('localhost', 1972) # might throw IOError H = ftc.getHeader() if H is Non print 'Failed to retrieve header!' sys.exit(1) print H print H.labels if H.nSamples > print 'Trying to read last sample...' index = H.nSamples - 1 D = ftc.getData([index, index]) print D if H.nEvents > print 'Trying to read (all) events...' E = ftc.getEvents() for e in print e ftc.disconnect()
