dump_layer_connections#

class brainpy.state.spatial.dump_layer_connections(sim, source, target, outname)[source]#

Write each realized edge’s endpoints, weight, delay and displacement (NEST DumpLayerConnections).

One whitespace-separated line per edge: src tgt weight delay dx dy [dz] where (dx, dy[, dz]) = target_pos - source_pos (the source-anchored displacement). Weight is in pA magnitude, delay in ms magnitude, coordinates in micrometres.

Parameters:

  • sim (Simulator) – The simulator holding the realized connections and positions.

  • source (NodeView) – The source and target populations/views (created with positions=...).

  • target (NodeView) – The source and target populations/views (created with positions=...).

  • outname (str) – Path of the text file to write.

Returns:

The written text (also persisted to outname), for direct assertion.

Return type:

str
