I found a solution

Great!

But just to help us better understand what the original problem was, could you please execute
grep -w kv *.mod
in the folder that contains your mod files, and tell us what it reported?

Comments: First, your code is still very much in the development and debugging stage. At this point there is no particular advantage to running long simulations, or even tens of short simulations. Start with a single simulation that lasts only long enough for one spike train--or even a quarter of a ...

why Spyder displays this message

implies launching from within Spyder. What does Spyder treat as the "working directory" and is there a way to make Spyder change that to the parent of the x86_64 directory?

I am trying to model the double cable circuit used by Wårdell et al 2019 I have no suggestions, having never seen the paper. Presumably the authors describe their methodology sufficiently clearly that correspondences between their parameters and those of NEURON's extracellular "mechanism"...

I know I can find the transfer impedance for a pure frequency What constitutes an impure frequency? What to do depends on whether you prefer to operate in the frequency domain or in the time domain. If you want to operate in the frequency domain, then for any pair of locations of interest you'll ha...

Comments: 1. Iteration over all sections is required because ena is a range variable, not a global variable. 2. Iteration over all segments is not required because the syntax sectionname.rangevarname = somevalue assigns the value "somevalue" to the range variable in all segments of the ref...

It's pretty straightforward in Python too. Try to think about the problem as being "how to iterate over all sections." This is easiest with the idiom for sec in h.allsec(): one_or_more_statements Example: suppose you have just created a bunch of sections and you need to insert hh into all ...

Thanks for following up on that.

What "myelin double circuit model" are you referring to? With regard to models of spike propagation in myelinated axons, many authors have published such models. Most of them use very simple representations of the electrical effects of the myelin sheath. Whether one is better than another ...

Those files are from an exercise that was part of the 2018 NEURON Summer Course. Download and expand this file
https://neuron.yale.edu/ftp/neuron/2018emory/course.zip
and you'll find all the files for that particular exercise in course/bulletin_board_py

The programs initbatser.py and initplotfi.py both need to use a procedure called plotfi, but plotfi is not built into Python. Instead, it is a user-written procedure that is defined in plotfi.py, which is in the same directory as initbatser.py and initplotfi.py. The statement from plotfi import plot...

There's a lot of "stuff" (code complexity) in that implementation of the Izhikevich model. It would be easier to incorporate simple representations of excitatory and inhibitory synaptic transmission, similar to ExpSyn and/or Exp2Syn, into your January 26 twocomps model. ExpSyn-like excitat...

It will be released when it's ready.

Sorry about that. The site's architecture has changed several times over the years, and some old URLs were not updated. The updated link is https://neuron.yale.edu/neuron/static/p ... p2.htm#3.2
