After some messing around I find that any clamping duration greater than half the timestep of the simulation invokes a response. I am guessing this stems from whatever half-step method NEURON uses to approximate the differentiial equations>?

Hi. I was wondering if it was possible to give an instantaneous current injection (not a hill function, but a delta function) with IClamp. Is the best I can do to set the duration of the clamp very very very low? I was also wondering how the program would deal with my setting the duration of the cla...

Hello, I am trying to make a very simple simulation where I have two sections which are connected. I put in constant DC current in the end of one of the sections, and I want to look at the steady state membrane potential distribution across both sections. I am using neuron in python. I have made a s...

I used this sequence of commands to install from source: #!/bin/sh #Install Neuron with InterViews and nrnpython interphase cd $HOME mkdir neuron cd neuron cd iv make distclean sh build.sh ./configure --prefix=/Applications/nrn71_x86_64/iv \ --build=x86_64-apple-darwin10 --host=x86_64-apple-darwin10...

I'm using OS X.6.2, i386, I was using python. I just tried nrrniv, and that works successfully...

you da man!

Hello, Sorry for all the questions; I am trying to just simply load up a .mod file via python. I have tried both the neuron.load_mechanisms and neuron.h.nrn_load_dll functions to no avail. In both cases I get this error: In [11]: h.nrn_load_dll('/Users/adamimos/Directory/umac/.libs/libnrnmech.so') l...

I am trying to use NetStim to give a train of current injections with specified max current. I have a netcon which has a NetStim as a source, and an exp2syn as a target. My understanding is that when NetStim passes NetStim.threshold, NetStim.weight will be sent to exp2syn, which will give current as...

I can't reproduce the problem on my osx 10.4 i686 machine. Both the standard 7.1 distribution and my latest sources are working for your test case. no problem, thanks for your help. after playing around with it a bit more, if you do from neuron import * at the begining, and then do from neuron impo...

Well in any case now, I've gotten acces to a linux box, so I should be good. However, it'd be helpful if anyone knew what was going on. Thanks. I'm not sure if this helps solve the mystery at all: every once in a while when I try "from neuron import gui" in python it will actually work, an...

hey, thanks for the reply. I'm actually using OS X.

I hate to just bombard with questions. But here is a more important problem: When i try to import the GUI i get this: In [1]: from neuron import gui MPI_Initialized==false, disabling MPI functionality.

Hey, I'm trying to use the graphing using neuron.h.Graph() as opposed to converting the data to a numpy array and then using pylab. In order to test things out I'm trying to use the most simple code to make a graph (which I pretty much copied from the NEURON and Python paper): from neuron import h s...

Thank you so much! I just had to change some very small things. It worked great!

Hey everyone, I'm just starting with NEURON and I installed from dmg and everything works fine. I am now trying to get NEURON working as a module within python. When I try to install from source I get a bunch of different errors depending on what I try. I tried this to install IV: IDIR=/Applications...
