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:

\verbatim embed:rst
============ ======== ========================================================
interval ms Recording interval
targets array Global id list of neurons to be observed
port_name string The name of the MUSIC input port to listen to (default:
cont_in)
port_width integer The width of the MUSIC input port
published boolean A bool indicating if the port has been already published
with MUSIC
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
============ ======== ========================================================

Availability:
Only when compiled with MPI and MUSIC
