Brian 1.3.1

We have just released Brian 1.3.1, available via easy_install -U brian or from our download page. This is a minor release, but there are some nice new features and many small improvements (listed below). Minor features:

  • New PoissonInput class
  • New auditory model: TanCarney (brian.hears)
  • Many more examples from papers
  • New electrode compensation module (in library.electrophysiology)
  • New trace analysis module (in library.electrophysiology)
  • Added new function to use multiple CPUs to perform multiple runs of a simulation and save results to a DataManager, with an optional GUI interface.
  • Added FractionalDelay filterbank to brian.hears, fractional itds to HeadlessDatabase and fractional shifts to Sound.shifted.
  • Added vowel function to brian.hears for creating artificial vowel sounds
  • New spike_triggered_average function
  • Added maxlevel and atmaxlevel to Sound
  • New IRNS/IRNO noise functions
  • SpikeGeneratorGroup is much faster.
  • Added RemoteControlClient.set(var, name) to allow sending data to the server from the client (previously you could only receive data from the server but not send it, except in string form).
  • Monitors do not process empty spike arrays when there have not been any spikes, increases speed for monitored networks with sparse firing (#78)
  • Various speed optimisations
Bug fixes:
  • Fixed bug with frozen equations and time variable in equations
  • Fixed bug with loading sounds using Sound(‘filename.wav’)
  • SpikeMonitor now clears spiketimes correctly on reinit (#75)
  • MultiConnection now propagates reinit (important for monitors) (#76)
  • Fixed bug in realtime plotting
  • Fixed various bugs in Sound
  • Fixed bugs in STDP
  • Now propagates spikes only if spikes exist (#78)
