Hi Barna, Yes, a Github issue would be useful.

Thanks for the speedy reply! With v3.2, using NodeCollections is successful: neurons = nest.Create('iaf_psc_exp', 2) nest.Connect(nest.NodeCollection([1]), nest.NodeCollection([2]), conn_spec='one_to_one', syn_spec={'synapse_model': 'static_synapse_lbl', 'synapse_label': 1}) However, when using arrays (as NodeCollection expects unique ids), I get the same error: neurons = nest.Create('iaf_psc_exp', 2) nest.Connect([1], [2], conn_spec='one_to_one', syn_spec={'synapse_model': 'static_synapse_lbl', 'synapse_label': 1}) Removing the synapse_label parameter also works. Should I open an issue on Github regarding this? Best, Barna On 2/2/22 7:48 AM, Hans Ekkehard Plesser wrote: Dear Barna, Could you try with NEST 3.2?

Is this the expected behavior or for some reason it's not possible to use synapse_label and the one_to_one rule (yet)?
