 +  <a href=/​reference/​ft_realtime_fmriproxy><​font color=green>​FT_REALTIME_FMRIPROXY</​font></​a>​ 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
 +    ft_realtime_fmriproxy(cfg)
 + 
 +  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
 + 
 +  To stop this realtime function, you have to press Ctrl-C
