Creating a new NodeCollection from Mask or by global_ids
by Kempter, Miriam 22 Mar '22

22 Mar '22

Dear Nest Team, working with Python 3.8 and Nest 3.2 my goal is, after creating a spatial NodeCollection "neurons", to create a new NodeCollection containing a selection of the node from "neurons". To achieve this I tried two different approaches: 1. Create a Mask object and use nest.SelectNodesByMask() nodes_in_mask = nest.SelectNodesByMask(neurons, ctr_position, mask_obj) 2. Transform the NodeCollection into a list of node ids, pick 3 random ids, and create a new NodeCollection containing those 3 Nodes neurons_list = neurons.tolist() for x in range(0, 3): center = random.choice(neurons_list) node_ids.append(center) node_ids.sort() new_collection = nest.NodeCollection(node_ids) But with both approaches I get the same problems that some Information (of the positions) seems to go missing. This shows in different ways. First the new NodeCollections are no longer spatial (nodes_in_mask.spatial and new_collection.spatial return none). Second trying to get the node Positions results in an Error: nest.GetPosition(nodes_in_mask) -> Error #1 nest.lib.hl_api_exceptions.LayerExpected: LayerExpected in SLI function GetPosition_g: And last, trying to Plot the Layer also results in an Error: fig = nest.PlotLayer(nodes_in_mask) -> Error #2 TypeError: 'NoneType' object is not subscriptable I attached a .txt file containing py code showing the problems. Why do those Problems occur and what can I do to solve them? Is there a way to create an empty NodeCollection s.t. I can add the wished nodes one by one? What exactly does the metadata of a Nodecollection represent? Is there a way to set it manually for example to spatial? Thank you in advance for your Answers, Miriam

NESTML, 'UnknownNode' model
by Alexander Kozlov 14 Mar '22

14 Mar '22

Hi, Any neuron model built with NESTML and installed via nest.Install('mymodule') receives 'UnknownNode' as the value for 'model': > nrn.get('model') > 'UnknownNode' Can this be ignored by users? Is it possible to set the value in .nestml file for compatibility with standard models? Best regards, Alex.

Error in NESTML when I run the 'NESTML Izhikevich tutorial'

Dear NESTML Users, In the last post I fixed a problem that was related to the fact that in the 'izhikevich_solution.nestml' the first line was commented.
