Dear Alex,

You are absolutely correct; NESTML is not aware of these parameters as they are "hard-coded" into the Archiving_Node. We are currently working on eliminating the Archiving_Node entirely, so that these parameters may be specified by a NESTML synapse and NESTML neuron model.

In the mean time though, you should still be able to access them via GetStatus() and SetStatus(). It looks like there is one crucial line missing from the NESTML neuron template: if you go to your NESTML installation directory, open the file pynestml/codegeneration/resources_nest/NeuronHeader.jinja2, and insert the following on line 524:

Archiving_Node::get_status( __d );

Then, setting and getting Archiving_Node parameters should work as expected:

>>> n = nest.Create("iaf_cond_exp_nestml")
>>> nest.SetStatus(n, "tau_minus_triplet", 42.)
>>> print(nest.GetStatus(n, "tau_minus_triplet"))

I will add this fix to the NESTML GitHub repository in short order.

Thanks for reporting this; please always feel free to post on this list about NESTML issues!

Kind regards,
