Hi,
My apologies for the confusing error message. It occurs because you have to explicitly
tell NESTML which postsynaptic neuron type it is connected to in the simulation. You can
see an example of that here:
https://github.com/nest/nestml/blob/003d17a6425c3f8d88ed3aedd8d8e1d76245966…
The port is then assigned as "postsynaptic" and it is not considered for the
error that you are seeing.
Please let me know if you run into any further trouble.
With kind regards,
Charl

Hello,
I am using an example synapse model which utilizes both post and pre spikes
(nestml/models/synapses/stdp_nn_symm.nestml at master · nest/nestml (github.com)
<https://github.com/nest/nestml/blob/master/models/synapses/stdp_nn_symm.nestml>).
I get an error:
...
File
"/dss/dsshome1/00/ge72puf2/.conda/envs/nest/lib/python3.8/site-packages/pynestml/codegeneration/nest_code_generator.py",
line 469, in _get_synapse_model_namespace
assert len(namespace["pre_ports"]) <= 1, "Synapses only support one
spiking input port"
AssertionError: Synapses only support one spiking input port
It is confusing: can I or can I not use a model with 2 synaptic inputs (post and pre)? Is
that a version thing?
Best regards,
