Two suggestions. First, regarding how to interpret neuromorphic representations of electrotonus: work through this exercise https://nrn.readthedocs.io/en/latest/courses/electrotonic_analysis.html#electrotonic-analysis << note added after my initial post: at present, the "Shape" link in the...

Hey! Relax, there's no need to be so formal. Is it possible to somehow define different axial resistances (Ra) for different ions? Everything is possible through programming, but the set of "everything" has many members that are ugly and awkward. You're asking for something that could eas...

error: invalid active developer path (/Library/Developer/CommandLineTools) There's your clue. Have you installed the Command Line Tools? If not, see https://apple.stackexchange.com/questions/107307/how-can-i-install-the-command-line-tools-completely-from-the-command-line These pulse generators prod...

One might well ask "How did ted make such an informed guess?" I now draw back the curtain of secrecy (faint of heart, pass not this line!) I executed nrngui then created an instance of the Multiple Run Fitter by clicking on NEURON Main Menu / Tools / Fitting / Multiple Run Fitter (of cours...

I found one post linking a model on modelDB that had a statement I suspect that one or more other statements must be executed before one tries to create an instance of the MulRunFitter class. Examine the source code for that entry in ModelDB (BTW, which entry is it?) and look for something similar ...

You're welcome. It works, but it should be much, much easier. It will take a while to figure out how to deal with Win 11.

Installing NEURON should have created a folder on your desktop that has a name that starts with NEURON. Double click on that folder. Inside the folder is an icon with the label "bash". Double click on that. That should open a bash terminal. The prompt will look something like bash-5.2$ At ...

I'm very sorry you had all this difficulty. Looks like Win 11 has created some new work for us.

You really need to have a detailed discussion with the person from whom you got these data. Here's what I found. I strongly suspect that the data are from an automated reconstruction, with minimal (if any) human supervision or intervention. That's an inference. What follows, however, is absolute fac...

For what it's worth

Might that also avoid the failure of neurondemo?

Are you using Windows 11? If not, what operating system are you using?

I used the Import3d tool to view a simple neuron (a soma with one dendrite), except the soma did not load.

This would mean there's something wrong with the morphology file. Is it publically available?

Try MBF ASCII file format. Use NEURON's Import3d tool. See https://nrn.readthedocs.io/en/latest/gu ... ort3d.html

Which XML do you have in mind? NEURON used to be able to import some flavors of NeuroML, but NeuroML (1) encodes a lot more than neuronal morphology, and (2) has been a bit of a moving target, so I'm not sure what NEURON can do with that currently. More recently, MicroBrightField introduced their ow...

Well, if the bash terminal is having problems under Win 11, maybe Anaconda will still work OK with NEURON. I can import neuron and run the GUI from Anaconda Prompt without any problem. What happens if you execute neurondemo in the Anaconda terminal? Does NEURON print a message that starts with "...
