Hello everyone,
I want to adapt two custom models called "global_volume_transmitter" and
"dopa_connection" from NEST 2.16 to NEST 3.1. The .cpp and .h files are
attached to this email. Is it possible to have the models adapted to
NEST 3.1? How could this be done?
I hope someone can help me with that.

Dear experts,
I have a question about using nest on docker/vscode on my windows PC. I
hope this is the right place to ask since I couldn't answer my question
using the troubleshooting session.
I am using docker to use pyNEST on my windows computer. I have successfully
installed NEST using the instructions mentioned here for installing on
docker:
https://nest-simulator.readthedocs.io/en/v2.20.1/installation/index.html.
If I am in the container, I have python version 3.8.10. If I run python and
then try to "import nest" it says there is no module named nest. Importing
other python packages works perfectly in this way. But indeed, when I look
at all the installed packages using pip list, there is no package called
"nest". There is, however "nest-desktop 3.0.3" there. So I guess nest is
not installed. However, I also don't know how to install it. If I use pip
install nest, another package called nest is installed that is not the nest
simulator (according to: #754
<https://github.com/nest/nest-simulator/issues/754>).
Also, I don't know whether this problem is related or totally unrelated but
it might give some insight: when I am in VScode in the nestsim/nest
container and I click on python: select interpreter, nothing happens, I
cannot select a python interpreter/no window opens. So maybe there is
something wrong with the python installations or the used path?
I hope the problem is clear. I've been trying different things for days so
I would greatly appreciate any help you can offer me!
Thanks in advance and have a nice day!
Kind regards,
Nina Doorn
Dear NEST Users & Developers!
I would like to invite you to our next fortnightly Open NEST Developer Video Conference, today
Monday 25 October, 11.30-12.30 CEST (UTC+2).
Feel free to join the meeting also just to bring your own questions for direct discussion in the in-depth section.
As usual, in the Project team round, a contact person of each team will give a short statement summarizing ongoing work in the team and 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.
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/2021-10-25-Open-NEST-Developer-…
Looking forward to seeing you soon!
best,
Dennis Terhorst

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
* Visit 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
- 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.

Dear all,
next month there will be another HBP CodeJam [1] coming up on Nov 23rd-26th and we think this might be an interesting occasion to meet and bring everyone up to the new possibilities now becoming available. The setup of models has become a lot simpler for example using NEST 3's object attribute access, and many models just need minor changes to make use of the powerful new syntax. Additionally the EBRAINS infrastructure has recently released very useful features that allow to combine different tools across the platform.
While the CodeJam is mainly advertised for service providers, it would be extremely helpful to have interested power users in the discussion to get direct feed-back for which features to specially prioritize. As far as I know the event is open to anyone with an EBRAINS account for which you can quickly register [2]. We can set up discussion slots also for discussing your use-case, questions or comments, and the event is also suited to work on real code and boost your project.
If you are interested for example to have a look into migrating your model to NEST 3, or if you have a particular topic you would like to discuss with NEST developers, or see what is possible on EBRAINS now, please register for the event and let me know! I'll try to gather the most productive set of people for those discussions.
(In case you create a new EBRAINS account for this CodeJam let me know, so I can have your account linked to the workshop – need to check…)
Looking forward!
Best,
Dennis

Dear all,
In my working group, we are working on the creation of the spiking
neural network of human CA1 (4.8 million neurons). We are using a
specific function for defining the connection between the neurons. This
function gives us 30 billion pairwise connections.
We would like to know what the most efficient for the creating the
network in NEST 3 using this pairwise connectivity.
Thank you in advance for your answer,

I've recently downloaded a new version of NEST, and I'm trying to make a new synaptic model, but am breaking down in building their default MyModule model. The process onhttps://nest.github.io/nest-simulator/extension_modules<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fnest.gith…> says to run bootstrap.sh, but I can't find a bootstrap.sh. Do you have a version you could send me? If not, who can I contact for help (and how)?

Dear NEST Users & Developers!
I would like to invite you to our next fortnightly Open NEST Developer Video Conference, today
Monday 11 October, 11.30-12.30 CEST (UTC+2).
Today we again have two possible topics for the in-depth discussion that you may be interested in:
* Plasticity models via NESTML, and
* NEST wheels (Python package mechanism).
As usual, in the Project team round, a contact person of each team will give a short statement summarizing ongoing work in the team and 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.
