[NEST Users] Using music_cont_in_proxy as current source

Dear all, I would like to receive a continuous stream of data via ‘music_cont_in_proxy’ and use it as input current to a neuron. I used ‘iaf_cond_alpha_mc’ as model neuron because I could specify the input that should target the neuron via the receptor_type that accepts current {‘receptor_type’: 7} (’soma_curr’: 7) and connected the ‘music_cont_in_proxy’ via this receptor to the neuron. Currently, for testing purposes, I used ‘constsource’ music binary continuous data stream, which is also used in NEST guides (https://bit.ly/2xBNfpO). As I imagined, it didn’t work maybe because the output type of the music port doesn’t match the input type of the receptor type (’the following error’). Does anyone know how I can overcome this problem (that I can use ‘music_cont_in_proxy’ as current source)? Thank you very much in advance. ########ERROR######## Traceback (most recent call last): File "./conttest.py", line 39, in <module> nest.Connect(mcip, mc, 'one_to_one', {'receptor_type': 7}) File "/local/work/Projects/closed-loop-learning/NEST/lib/python3.7/site-packages/nest/ll_api.py", line 246, in stack_checker_func return f(*args, **kwargs) File "/local/work/Projects/closed-loop-learning/NEST/lib/python3.7/site-packages/nest/lib/hl_api_connections.py", line 362, in Connect sr('Connect') File "/local/work/Projects/closed-loop-learning/NEST/lib/python3.7/site-packages/nest/ll_api.py", line 132, in catching_sli_run raise exceptionCls(commandname, message) nest.ll_api.UnexpectedEvent: ('UnexpectedEvent in Connect_g_g_D_D: Node cannot handle received event.', 'UnexpectedEvent', <SLILiteral: Connect_g_g_D_D>, ': Node cannot handle received event.’) ########ERROR######## Best wishes, Mohammad -- Mohammadreza Mohagheghi Nejad Postdoctoral researcher in computational neuroscience, Institute of Neural Computation, Ruhr University Bochum, Germany https://www.ini.rub.de/the_institute/people/mohammadreza-mohagheghi_nejad/
