Installing an extension module in tvb-nest docker

Dear experts, To develop a spiking neuronal network model of the thalamus, I want to adapt the Izhikevich neuron model to account for the behavior of thalamocortical neurons. 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 . I am working with the tvb-multiscale docker container ( https://github.com/the-virtual-brain/tvb-multiscale/tree/master/tvb_multisc…) 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. I've succesfully "made" the module with: > docker@84fabd16af99:~/mmb$ cmake > -Dwith-nest=/home/docker/env/neurosci/nest_build/bin/nest-config > ../nest-extension-module-master It gives me the message: > You can now build and install 'mymodule' using > make > make install > The library file libmymodule.so will be installed to > /home/docker/env/neurosci/nest_build/lib/nest/ > Help files will be installed to > /home/docker/env/neurosci/nest_build/share/doc/nest > The module can be loaded into NEST using > nest.Install('mymodule') (in PyNEST) > (mymodule) Install (in SLI > -- Configuring done > -- Generating done > -- Build files have been written to: /home/docker/mmb However, when I try to "make". I get a bunch of errors that I have added at the end of this email. My colleague tried to install exactly the same module in exactly the same way on his linux machine and it worked perfectly. But somehow for me, I get these weird errors that I haven't been able to resolve so far. Does anyone have an idea what the problem might be? It would be greatly appreciated. If you need any additional information please let me know. Thank you in advance and have a nice day!

Using NEST in Spyder/anaconda
by Julien Ballbé 10 Nov '21

Dear Sir, Dear Madam, I am currently trying to install NEST in order to be able to use it within an IDE, like Spyder. For the moment I am only able to do the following: open Terminal python3 import nest This works when I use it in the terminal of the computer, but when I open Spyder and execute the following: import nest neuron=nest.Create("iaf_psc_alpha") neuron.get() I get the following error message in the IPython console: runfile('/Users/julienballbe/NEST/untitled0.py', wdir='/Users/julienballbe/NEST') Traceback (most recent call last): File "/Users/julienballbe/NEST/untitled0.py", line 11, in <module> neuron=nest.Create("iaf_psc_alpha") AttributeError: module 'nest' has no attribute 'Create' I am using a Macbook pro M1Max, MacOS 12.0, Spyder 5.1.5, Python 3.9.7. I followed the instruction for building nest on your website ( https://nest-simulator.readthedocs.io/en/latest/installation/mac_install.ht…) and used your recommendation for M1 macs ( https://nest-simulator.readthedocs.io/en/latest/installation/conda_tips.html ). I build Nest following your instruction, the only error I got was when I ran : (nest-simulator-dev) julienballbe@pclnrs241 NEST % make installcheck NEST Testsuite Results

NeuronUnit interface to NEST Adexp model.
by Russell J. Jarvis 10 Nov '21

10 Nov '21

Hi there NEST community, I am trying to build an interface between [NEST reduced cell models (Izhikevich/AdExp) and NeuronUnit](https://github.com/russelljjarvis/NESTNeuronUnit). For example here is one such [interface](https://github.com/russelljjarvis/NESTNeuronUnit/blob/master/nes… ) I find that if I run a single current injection experiment using the interface I get an expected number of spikes, but if I keep re-using the same interface in more and more experiments I get the same or similar number of spikes even with different current injection values. Its as if the initial conditions of the model are not re-setting properly. I wonder if there are any ideas of things I could check. This [simple file works okay](https://github.com/russelljjarvis/NESTNeuronUnit/blob/master/test_int…, but it only has one simulation run. Russell Jarvis (he,him) PhD Neuroscience [Personal Website](https://russelljjarvis.github.io/home/) I acknowledge the Dja Dja Wurrung and Taungurung Owners and Custodians of the lands on which I live and work and pay my respect to Elders past, present and future. phone: 61444576301 email: russelljarvis(a)protonmail.com Sent with [ProtonMail](https://protonmail.com/) Secure Email.

Get details of source and target from Connection list
by Maryada Maryada 09 Nov '21

09 Nov '21

Dear NEST users, In the past version, for debugging purposes I used to get information of my source and target using the GetStatus function. However, with NEST 3.0, I couldn't find a way to do so, mainly because I have to pass either a SynpaseCollection or NeuronCollection as a function argument to GetStatus. Is it possible to fetch node collection from neuron id? Or any easier way to get source and target properties. I referred document at link https://nest-simulator.readthedocs.io/en/v3.1/guides/connection_management.… I have attached the python file for the same. -- Thanks, *Maryada*

Open NEST Developer Video Conference Monday 8 November 2021 11:30 CET (UTC+1)
by Dennis Terhorst 08 Nov '21

08 Nov '21

Dear NEST Users & Developers! I would like to invite you to our next fortnightly Open NEST Developer Video Conference, today Monday 8 November, 11.30-12.30 CET (UTC+1). 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/2021-11-08-Open-NEST-Developer-… Looking forward to seeing you soon! best, 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 * 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. For more technical information on logging in from various VC systems, please see http://vcc.zih.tu-dresden.de/index.php?linkid=1.1.3.4

NEST on macOS 12 Monterey
by Hans Ekkehard Plesser 04 Nov '21

04 Nov '21

Dear NEST Users, I would just like to let you know that I have successfully built, installed and tested NEST on macOS 12.0.1 (Monterey) on Apple Silicon, following the standard procedure for the Mac. Both Apple Clang 13.0 and G++ 11 work. Note that there have been some reports that upgrading to macOS Monterey can very thoroughly lock your machine, especially Intel-based machines (https://arstechnica.com/gadgets/2021/11/why-macos-updates-might-brick-your-…), so you may want to wait with upgrading until this is solved. Best, Hans Ekkehard -- Prof. Dr. Hans Ekkehard Plesser Head, Department of Data Science Faculty of Science and Technology Norwegian University of Life Sciences PO Box 5003, 1432 Aas, Norway Phone +47 6723 1560 Email hans.ekkehard.plesser(a)nmbu.no<mailto:hans.ekkehard.plesser@nmbu.no> Home http://arken.nmbu.no/~plesser
