Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_realtime_fmriproxy”.

  FT_REALTIME_FMRIPROXY simulates an fMRI acquisition system by writing volumes in a
  cycle of about 2 seconds. The voxel data is written as a column vector with X*Y*Z
  channels, where X and Y are the readout and phase-encoding resolution, and Z is the
  number of slices. The voxel data consists of a ellipsoid (a bit like a head) with
  added lateralized activation (20 scan cycle) and noise.
  This function also writes out events of type='scan' and value='pulse' when the
  simulated scanner initiates a scan, and value='ready' when a hypothetical
  processing pipeline is finished with that scan, just after writing out the volume
  data itself. There is an artificial delay of 1.3*TR between the two events.
  Use as
  The target to write the data to is configured as
    cfg.target.datafile      = string, target destination for the data (default = 'buffer://localhost:1972')
  You can also select a resolution of the simulated volumes (default = [64,64,20]) like
    cfg.voxels = [64 64 32]
  and the repetition time (TR, default = 0.08*number of slices) in seconds using
    cfg.TR = 2.0
