log data into data_path
by Benedikt Feldotto 21 Jan '22

21 Jan '22

Dear all, quick question about data logging to a specified folder: with nest.SetKernelStatus({"data_path": '/opt/data/log'}) I can specify the path, where data is logged to. If I do not specify a path, where does data get saved, or is it not saved to file if I do not specify 'data_path'? Thanks! Benedikt -- Benedikt Feldotto M.Sc. Research Assistant Human Brain Project - Neurorobotics Technical University of Munich Department of Informatics Chair of Robotics, Artificial Intelligence and Real-Time Systems Room HB 2.02.20 Parkring 13 D-85748 Garching b.

how do I record events emitted by "sinusoidal_poisson_generator"
by thierry nieus 03 Jan '22

03 Jan '22

Dear all, first of all, happy new year! I am using nest 2.2 (installed by conda) and I have set up a simple network of 20-100 neurons based on the ht_neuron model. I am delivering some noise to all neurons with the sinusoidal_poisson_generator (I can switch to another) and the simulation produces the results I am looking for. However I would like now to have a look at the spikes entering the network and therefore I need to access all events generated by the random generator. A sample of my code is: import nest receptors=nest.GetDefaults('ht_neuron')['receptor_types'] nest.CopyModel("sinusoidal_poisson_generator",'sin_pois',{'amplitude':50.,'rate':15.0 }) nest.CopyModel("static_synapse","AMPAnoise",{"receptor_type":receptors["AMPA"],"weight":10. }) neurons=nest.Create("ht_neuron",1) noise=nest.Create('sin_pois',1) g = nest.Create('sin_pois', 1) # current pulse dc_gen = nest.Create("dc_generator") nest.SetStatus(dc_gen, {"amplitude": 20., "start": 400, "stop": 1050}) nest.Connect(dc_gen, neurons, 'one_to_one') # recorders detect_noise = nest.Create('spike_detector', 1) nest.Connect(noise, neurons, 'one_to_one', syn_spec="AMPAnoise") nest.Connect(noise, detect_noise, 'one_to_one') ''' the latest does not work Creation of connection is not possible because: All outgoing connections from a device must use the same synapse type. ''' Is there a way to record those spikes ? Thanks in advance for any help Best
