Dear NEST Users & Developers!
I would like to invite you to our next fortnightly Open NEST Developer Video Conference today
*Monday July 29, at 11:30 CEST (UTC+0200).*
As usual, in the Project team round, a contact person of each team will give a short statement summarizing ongoing and planned work in the team and highlight cross-cutting points that need discussion among the teams. The remainder of the meeting we would go into a more in-depth discussion of topics that came up on the mailing list or that are suggested by the teams.
Feel free to join the meeting also if it’s just to bring your own quick questions for direct discussion in the in-depth section.
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/2024-07-29-Open-NEST-Developer-… <https://github.com/nest/nest-simulator/wiki/2024-07-29-Open-NEST-Developer-…>
Looking forward to seeing you soon!

Log-in information
We use a virtual conference room provided by DFN <https://www.dfn.de/en/> (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
* Visit https://conf.dfn.de/webapp/conference/97938800 <https://conf.dfn.de/webapp/conference/97938800>
* Enter your name and allow your browser to use camera and microphone
* The conference does not need a PIN to join, just click join and you’re in.
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:97938800@vc.dfn.de <mailto:97938800@vc.dfn.de>
* 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

Dear NEST Users,
Could anyone recommend the best way to inject a fluctuating current over
time.

Hello everyone,
I am trying to replicate our brain-constrained model to NEST.
In our model the computation of the inhibition occurs before the inhibition.
I believe it's the other way round in NEST.
I was wondering, where the order of computation was implemented in NEST and if that was possible to change it.
Best,
Maxime

I'm working with the nestml 7.0.2. I got the example models from https://github.com/nest/nestml/blob/v7.0.2/models/neurons/hill_tononi.nestml this git tree. I tried three different stdp models including stdp_triplet_naive.nestml. All give
AssertionError: Synapses only support one spiking input port
when I generate_target in python.

I've taken your noisy_synapse model and got that to run in pyNest. When I try it in PyNN it fails (can't find weight if you set w, weight not an argument if you use weight). I understand that you don't support pyNN. Do you support SpiNNaker (as it's a target)? If so, how do you access the model on SpiNNaker? (I only access SpiNNaker through PyNN).
-Chris
I was using an old version of nest (3.5) and nestml. Someone sent me a nestml model, and that worked. I wanted to make my own model, but the tutorials had a different format. In particular, it seems like the first line of code in the tutorials start with model, and the old version started with neuron of synapse.
So, I thought it was time to upgrade, so installed nest 3.7, and pip-ed nestml. (I also installed PyNN as that's the way I typically work.) When I imported generate_target (through python 3.12), I got the typical PyGSL warning; I think that's because I'm using python 3.12 not 3.11, and I don't think it matters in this case.
Then I ran the generate_target and I got an error mismatched input 'model' expecting {newline, 'neuron', 'synapse}
I expect there's something like a yacc table that specifies the syntax, and somehow I've got the old syntax.
I've tried it with several version of nestml 7.0.2, 7.0.0, 6.0.0 and 5.0.0. I think 5.0.0 had the old syntax. I've tried several models from the library, and the Izhikevich tutorial.
Any thoughts about how to fix it?
