Hi ramcdougal, Could you explain the derivation of the scale factor here? Why is the electron charge in the factor? I would have guessed Avogadro's number would have something to do with it. Why 1e-14? um2 is 1e-12 m2, is that related? e = 1.60217662e-19 scale = 1e-14 / e # rate constant is in terms...

OK, I can mark this as resolved now ... I restarted the computer and the same code works now. I have NO idea what happened.

Strange indeed. Maybe something in this code I am using has changed throughout different NEURON versions? Hopefully something easy to spot. Here is the code. It is a class that creates a spiny projection neuron (also medium spiny neuron, hence the class name MSN). I am pasting just the beginning of ...

Hello everyone! I just installed NEURON 8.0 on a fresh installation of Ubuntu 20, and am trying to run already existing code. While loading a morphology of a spiny projection neuron I get the following error which did not appear on my previous installation of Ubuntu and NEURON. I am wondering if I h...

How (not) helpful. Under Linux Mint (a close cousin of Ubuntu), pip install of NEURON simply adds .local/bin to PATH, and everything works properly without the user having to do anything to PATH. Yes, I also got the impression that the user does not need to do anything after "pip3 install neur...

I installed Ubuntu 20 anew and I think I realized how an earlier version ended up getting installed. After installing NEURON with pip3 install neuron I didn't add it to the path. At trying to compile mod files Ubuntu prompts me to install neuron-dev with sudo apt which was version 7.6.3. I must have...

Hi again Ted! It seems I have been editing the previous post while you were writing your answer. (I also realized while re-reading your first response that the entire output is not there and went on to edit the post to include NEURON's version. Also commented there that I installed NEURON according ...

Hi Ted! Thank you very much for your quick reply. Here is the output: NEURON -- VERSION 7.6.3 master (85d62db) 2018-11-21 Duke, Yale, and the BlueBrain Project -- Copyright 1984-2018 See http://neuron.yale.edu/neuron/credits loading membrane mechanisms from /home/daniel/Documents/PhD Studies/Work/Pl...

Hello everyone, I am trying to load compiled mechanisms with: h.nrn_load_dll('./mod/x86_64/.libs/libnrnmech.so') and am getting this error: dlopen failed - /usr/lib/x86_64-linux-gnu/libnrniv.so.0: undefined symbol: nrnpython_start Anybody has an idea what this means and how to fix it? I read online ...

OK, thank you.

It is a very good friend, indeed, but this time I couldn't find the answer in the documentation of the Vector class.

Hello to everyone,

my question is about the following scenario. Say we have a vector that is recording from some variable. Is there a way to check what the vector is recording from, like, an attribute or a method in the vector class that returns this information?

Best regards

Thank you so much! I wouldn't have guessed.

Hello to all! When trying out a ball-and-stick model, one written using nrnpython and the other using HOC, I get different results from each of them. I think I have written the equivalent code statements in each example, and I can't see what is going wrong. The codes are below, and I can send the fi...

The answer to the question - I didn't find any at the time, but yes, I didn't look thoroughly. Alternatively, yes, starting with the AMPA_S mechanism sounds like the way to go. Thank you!
