Re: Error after install NEURON 8 using rxd

...and another detail I have noticed that might mean something is that when running (specifically when finalizing h.finitialize(-58)) just as it dies and throws that error... I noticed a file such as this is created every time:

Re: PyCharm "ModuleNotFoundError: No module named 'neuron'"

I am just a bystander here, but since I do have NEURON (7.6) working well with PyCharm, using an Anaconda environment on one of our Macs, I thought perhaps I would paste up the all important configuration I have: Script path: /Users/richardbarrett-jolley/Documents/NEURON25/model.py Parameters: None ...

Re: Error after install NEURON 8 using rxd

Thank you, so NEURON 8.0, This is Python 3.8 calling a NEURON model from within an ANACONDA (py3.8) environment. With Spyder in fact. (but same with a simple terminal in the same environment). gcc looks good? Using built-in specs. COLLECT_GCC=/usr/bin/gcc COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-pc-c...

Error after install NEURON 8 using rxd

The error itself is this: Could not find module 'C:\Users\Richard\model\rxddll201f5865-89a7-11ec-9fad-f48c5065050d.so' (or one of its dependencies). Try using the full path with constructor syntax. Then this: ld: error: c:/nrn/mingw/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64...

Preproducing updating PlotShape() figures in

Hi All, I have had some success with accessing the PlotShape() function through Python in Jupyter and up dating it so I can see a pretty coloured wave of Vm traversing my test model (based on your own tutorials). To moviefy this, I can screen record it, however, usually with Python in other projects...

Re: How to cite NEURON

Hi there, Noticed that "https://neuron.yale.edu/neuron/nrnpubs" is a Page Not Found... should point to-> https://www.neuron.yale.edu/neuron/publications/biblio Also, unless you have a way to automate this or "Crowd source it" this may be a fantastical idea, but I wondered if you ...

Making a Nucleus

Hi so in a previous post I mentioned that I had been defining a no go zone in the middle of my cells by creating a region with zero diffusion. I can't get that to work, so next I have tried using h.pt3dremove() to "bite" a nucleus out of the cell. That doesn't work for me: h.pt3dremove(int...

Re: Node.d (Diffusion) for Node3D objects

Sorry for the delay in my reply to your reply! Firstly, the nthreads thing; I am just wrong. There seems to be an optimal number of threads. Might work out to be the cores or something I don't know, but I was wrong to say it slowed it down of course. Must of been changing several things at the same ...

Node.d (Diffusion) for Node3D objects

Hi there, is this my understanding or an issue.. If I create my mode in 1D, my species.nodes have a diffusion value node.d that I can either read or write to... ...but if I do the same with 3D models, I find that node.d is unread or writable? Well it seems to be a string not a float value anyway. I ...

Re: Modelling a channel with multiple markov states

Sorry, my RXD models use pointers to gate channelbuilder channels with temperature not Ca[er]. So that approach may work with your problem, using Ca[er] instead of temperature... but look I am just a regular NEURON user, not an expert, so lets see what the experts say :-) If "your" method ...

Re: Modelling a channel with multiple markov states

...Interesting, I didn't realise that was a feature of RxD, my Markov channel models are built with Channel Builder and then imported into my code (that includes RxD). I will interested to hear the answer to this enquiry also.
