Re: mknrndll does not work correctly

Hi Ted,

It works! You are right. I did install it before, and the first uninstallation was not completed because I did it in control panel. Now I followed your suggestion and removed all the related stuff in Registry before the reinstallation and it works. Thanks!

Re: mknrndll does not work correctly

Hi ted, Thanks for your reply. Let me make sure that I know which "latest version" you installed. Did you use one of the NEURON installers (a nrn...exe file)? If yes, what is the name of that file? Or did you build NEURON from source code? I use the file named "nrn-7.4.x86_64-w64-mingw32-setup" and ...

mknrndll does not work correctly

Hi,

I have just installed the latest version of NEURON v7.4. However, when I open the mknrndll to compile the mod code, it hangs up cannot continue. The installation is complete. The nrngui works okay. Do I miss any file? Could you please help answer it? Many thanks!

Re: voltage propagation in the whole cell

Hi Ted,

Thanks for your reply! I actually want to see the voltage distribution in the whole cell, for example, as the movie shown below

Thanks!

voltage propagation in the whole cell

Hello, I have downloaded a NEURON code and want to add a few lines to visualize the voltage propagation from a synaptic input site to the rest part of the neruon as time evolves. So far I only found some functions such as "Shape/PlotShape", but I am not sure whether they work or not. Can anyone tell...

Re: voltage clamp with high holding potential

I set the density of the sodium channel a little smaller and it works now. Ted, thanks a lot for your helpful answer!

Re: voltage clamp with high holding potential

Dear Ted, Thank you so much for your reply! VSClamp? What's a VSClamp? Did you mean SEClamp? Yes, I mean SEClamp. Sorry for the typo. Are the biophysical mechanisms implemented with the ChannelBuilder or with NMODL? They are implemented with NMODL. Models that involve persistent inward sodium curren...

voltage clamp with high holding potential

Hello, I built a multi-compartment neuron model with active channels. I want to measure the inhibitory synaptic current at the soma using Voltage clamp. I first used VSClamp to hold the voltage at the soma at 0mV (excitatory reversal potential) starting from 0ms to 500ms. Then I gave the neuron an i...

recording axial current

Hi, I wonder if it is possible to record the internal axial current between two compartment/segment? For instance, I want to record all the current sources in the soma, and I can have soma.ina, soma.ik, etc to record all types of ionic current, but I do not know how to record the axial current flowi...

Re: Problems running NEURON

Hi Ted, I try to follow your procedure, it's okay that I can run nrngui after enter the command export PATH=/Applications/NEURON-7.3/nrn/x86_64/bin But when I try to use ls -a , the terminal returns command not found. It seems I cannot use any command after the export. Do you have any idea how to co...

Re: problems compiling .mod

Hi Mike,

You are right. If I drag the file directly onto the icon, it works! If I first double click the icon and then drag it onto the window, then nothing happens. I guess that might be a problem other people will meet. Thanks for your reply.

Re: Problems running NEURON

Hi Ted,

Thanks for your reply! Your guess is exactly right, I installed NEURON from the dmg.

If I enter the command echo $PATH in the terminal, the following shows up,

applematoMacBook-Pro-3:~ apple$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin

I can run nrngui, load hoc files and run neurondemo in either the version I already had loaded or the one you posted just now. The only thing I've found that does not work is generating nrnmech.dll etc. from a ...

Problems running NEURON

Hi, I have installed NEURON v7.3 in my Macbook with OS X 10.7.5. And I have installed the Xcode v4.5 as well as the latest version of the command line developer tools to compile mod files as suggested. The problem is, when I try to use terminal to run it, it shows "-bash: nrnivmodl: command not foun...
