Re: Morphology import error
Thanks so much for taking the time to explain me the problem. The morphology as viewed using Neurolucida/HBP Neuron Morphology viewer looks good without any issues. I don't see any point which is not connected to the parent. Only when I import it in NEURON, there are a few points without any parent....

Morphology import error
I am trying to import a morphology (from an .swc file) through cell builder. NEURON says that there are file translation problems. The terminal emits an error message saying that there is more than one tree. Any information on this appreciated.
Thanks in advance
Thanks in advance

Re: Inconsistent units
The previous primary expression with units: 1 kg/m3-sec is missing a conversion factor and should read:
(6.02217e+026)*() at line 54 in file updateo2o.mod
(6.02217e+026)*() at line 54 in file updateo2o.mod

Inconsistent units
Hi all, I have this mod mechanism to compute local oxygen concentration from bath oxygen concentration and from the activity of Nakpumps in neuron and glia. The mod file compiles without any error. However, running this script with modlunit returns a conversion error which I couldn't understand. Any...

Mapping of hoc toploogy and 3D morphology
I recently exported a .asc file and created a hoc template. Everything works well, thanks to this forum and the well documented procedures on how to use import3D. I am recording transmembrane currents from certain compartments/segments. I have the morphology plotted using the trees toolbox. I need t...

Display time as the simulation progresses
I am running a network model in using Parallel NEURON. I want to display the following while the model is running: The "biological" millisecond and the real time taken (in seconds) to run for that particular millisecond, FOR EACH HOST. For example, if running on 3 hosts, "running mill...

Mknrndll help
I am new to using NEURON on Windows..
I installed NEURON on my Windows Desktop. When I typed mknrndll (after cding to the folder where my mod files are) it doesn't recognize the command. It says "mknrndll is not recognized as an internal or external command". Can someone help ?

Segmentation violation error
Hello, I am trying to run my single cell multi-compartmental model. The problem is, when I change the temperature of my model (even by 1 degree either by increasing or decreasing ) I get this strange segmentation violation error. /Applications/NEURON-7.3/nrn/x86_64/bin/nrniv: Segmentation violation ...

Re: Problem with saturating synapse model
Is this bug fixed ?While a fix for this is being developed (allow specification of the self-event that is to be moved?), the interim workaround is to limit each instance of the saturating synapse mechanism AMPA_S to a single input stream per instance--that is, one NetCon per AMPA_S instance.

Re: Axial currents between two compartments
The documentation of 'ri' says that it returns the resistance (in megohms) between the center of the segment containing x and its parent segment. First of all, I don't understand how NEURON computes the parent segment of a section. How could the resistance at the point of connect between soma and de...

Axial currents between two compartments
Consider we have two sections soma and dend and connect them in the following way: connect dend(0),soma(0).
If I print the axial resistance (ri) at soma(0) and dend(0) it says 1e30. Does it mean that there is no flow of current between these points ?
