# Command: music_cont_out_proxy

NEST HelpDesk | Command Index | NEST Quick Reference

Name:

    music_cont_out_proxy - A device which sends continuous data from NEST to
      MUSIC.

Description:

    A music_cont_out_proxy can be used to send continuous data from
      neurons over MUSIC to remote applications. It works in a similar fashion like
      the multimeter model. The user has to specify the recordable values to observe
      (e.g. ["V_m"]) via the record_from parameter. The target neurons are specified
      by a list of global neuron ids which must be passed via the "targets"
      parameter. The music_cont_out_proxy will be connected automatically to the
      specified target neurons. It is not possible to apply further changes to the
      list of target neurons or observed quantities once the simulation has been
      started for the first time.

      In case of multiple recordables the data can be read out (PyNEST only) of the
      receiving buffer via the following access pattern:

      buffer[ target_gid_index ][ recordable_index] = buffer[ target_gid_index *
      record_from.size() + recordable_index ]
      For example:  target_gids = [ 2, 5, 4 ], record_from = ["V_m"] and
      we want to get "V_m" for neuron with GID 5: buffer[ 1*1 + 0 ]

Parameters:

      The following properties are available in the status dictionary:

      interval	 double  	- Recording interval in milliseconds
      targets	 array  	- Global id list of neurons to be observed
      port_name   string  	- The name of the MUSIC output port to send to
      (default: cont_out)
      port_width   integer 	- The width of the MUSIC input port
      published   bool		- A bool indicating if the port has been already
      published with MUSIC. Read only property.
      record_from  array  	- Array containing the names of variables to record
      from, obtained from the /recordables entry of the
      model from which one wants to record

Require:

    HAVE_MUSIC

Availability:

    Only when compiled with MPI and MUSIC
