Hello Thanh Binh To,

I see that the NESTML version you are using is quite old. Could you please install the latest version (7.0.2) and try again? You can install that using the command “pip install nestml”.

Please note that the module name should end with the suffix “module”. Therefore, your module name should be “iaf_psc_exp_nonlineardendrite_module” with an “e” at the end.

Regards,
Pooja

Dear Pooja,
 
Yes I change the name of NEST-module to "iaf_psc_exp_nonlineardendrite_modul"

I do not know which ATN version should work ...
 
Thanks and BR

Betreff: [NEST Users] Re: Problem by generating my nestml
Hello Thanh Binh To,
 
From the list of target files you have shared, the module name for the generated code is “nestmlmodule”. So in your simulation script, you must install “nestmlmodule” and not “iaf_psc_exp_nonlineardendrite”.
 
nest.Install(“nestmlmodule”)
nest.Create(“iaf_psc_exp_nonlineardendrite”)
 
You do not need to copy the .so file manually as the generate_target() call already copies it to your install_path. Hope this helps!
 
Regards,
Pooja

Dear all,
 
thanks you for very nice meeting today.
 
I use the following Python script for generating and compiling my NESTML-neuron model.
It runs and provides the following files in my target order (see my snapshot)
#########################
iaf_psc_exp_nonlineardendrite.h
iaf_psc_exp_nonlineardendrite.cpp
nestmlmodule.h
nestmlmodule.cpp
nestmlmodule.so

##### my python script
import sys

nest.Install("iaf_psc_exp_nonlineardendrite")

But I really do not know
1. where to copy nestmlmodule.so to?
2. What to do with generated C++ and *.h files? Copy to to the folder "models"??
 
Then I run other Python script to create a  neuron (see my modified verion structural_plasticityB.py), and have got errors like

Please check the modeldict for a list of available models. A frequent cause for this error is that NEST was compiled without the GNU Scientific Library, which is required for the conductance-based neuron models.

Can anyone help me?
 
Thanks

Betreff: [NEST Users] Open NEST Developer Video Conference Monday June 3, at 11:30 CEST (UTC+0200)

Dear NEST Users & Developers!

I would like to invite you to our next fortnightly Open NEST Developer Video Conference today

Monday June 3, at 11:30 CEST (UTC+0200).

Despite many people attending conferences this week, we will briefly meet to offer attention also to smaller questions or more general topics that you may bring. The Project team round, might however be quite short today.

Feel free to join the meeting and bring your own quick questions for direct discussion or just to hear what's going on in and around NEST.

Agenda

  • Welcome
  • Review of NEST User Mailing List
  • Project team round
  • In-depth discussion

The agenda for this meeting is also available online, see https://github.com/nest/nest-simulator/wiki/2024-06-03-Open-NEST-Developer-Video-Conference

Looking forward to seeing you soon!

Cheers,

Dennis Terhorst

Log-in information

We use a virtual conference room provided by DFN (Deutsches Forschungsnetz).

You can use the web client to connect. We however encourage everyone to use a headset for better audio quality or even a proper video conferencing system (see below) or software when available.

Web client

In case you see a dfnconf logo and the phrase “Auf den Meetingveranstalter warten”, just be patient, the meeting host needs to join first (a voice will tell you).

VC system/software

How to log in with a video conferencing system, depends on you VC system or software.

  • Using the H.323 protocol (eg Polycom): vc.dfn.net##97938800 or 194.95.240.2##97938800
  • Using the SIP protocol:
  • By telephone: +49-30-200-97938800

For those who do not have a video conference system or suitable software, Polycom provides a pretty good free app for iOS and Android, so you can join from your tablet (Polycom RealPresence Mobile, available from AppStore/PlayStore). Note that firewalls may interfere with videoconferencing in various and sometimes confusing ways.

For more technical information on logging in from various VC systems, please see
