Dear Charl,
While trying to obtain the minimal code to reproduce the problem, I found out the problem
disappears when I get rid of the setting of the timestep.
At the beginning of the script, I have (because sometimes I want to have the timestep
smaller):
nest.ResetKernel()
dt = 0.1
nest.SetKernelStatus({"resolution": dt, "print_time": True})
And at the meters"
TCmeter = nest.Create("multimeter",params={"interval": dt})
Although getting rid of this last part at the meters doesn't solve the problem.
In the documentation, I cannot find a change between nest 2.18 and nest 3.1 concerning
the resolution. Did I miss something?
Also, setting the clock back to zero doesn't work anymore"
nest.SetKernelStatus({'time':0.})
and I haven't found how I am supposed to do this in NEST 3.
I hope the question is clear. Thank you so much for all your help.
Best,
Nina

Dear Nina,
If you could provide us with a small, self-contained script that reproduces the issue,
that would be great to help with debugging.
Cheers,
Charl

In this container, I can easily install the example nest-extension module, exactly like is
explained in the tutorial. Thus, the problem was indeed with the nest version.

script to simulate the response of a few unconnected different
aeif_cond_alpha_multisynapse neurons to a transient input current. If I run this script in
the old setup, it works perfectly and runs in under a second. However, if I run it in the
new setup, simulations take forever (I haven't been able to finish one).

possible with the available NEST models. However, what I have done so far with the
aeif_cond_beta_multisynapse, is to define different receptors with different time
constants corresponding to AMPA, NMDA and GABA post-synaptic potentials. This would not be
possible with the NEST models you mention above. However, I will definitely take a look at
them and re-evaluate the importance of modelling these different beta-synapse receptors.

Before I do this, I wanted to test if it was possible to install an extension module in my
setup. Therefore I followed these steps:
https://nest-extension-module.readthedocs.io/en/latest/extension_modules.ht… to install
this example nest-extension-module:
https://github.com/nest/nest-extension-module .

in VScode on windows. I've been working with this succesfully and easily managed to
make thalamus models with the available aeIF neuron model of NEST. I'm using a python
3.7.3 interpreter and NEST 3.
