Different Levels of Access?
Hi, I am using the latest NEURON 7.1 on my MacBook Pro.. I was just wondering what the difference between the two pieces of code are: create soma soma { objref test test = new IClamp(0.5) } producing an error: /Applications/NEURON/nrn/i686/bin/nrniv: syntax error in test.hoc near line 5 test = new I...

changed dt
I am running a simulation on many parallel machines and each of them calculates a voltage trace with a variable time step..
During this simulation my screen is filled with hundreds of "changed dt"..
Is there a way to get rid of that output??
Thank you,
Armin

Re: ParallelPython and Neuron
Thank you -- a system based on mpi seems to be the better way to do for the future.. I will give ipython a try.. However I have been able to use parallel python with neuron.. The nice thing is that you could use it on every computer where you can install normal neuron and python (even within www). N...

to_python() causes big memory problems
Since the new version (6.2.3) came out I am using the to_python function to copy neuron vectors to python arrays.. The function to_python seems to allocate new memory that it never gives free again.. I wrote a simple example to illustrate this problem. (Points are spaces below) Example 1: 16GB Memor...

Re: Install nrnpython when Python is in home
Hi Michael, Unfortunately, all combination of pylib and pyinc, etc... yield the same effect when I try to configure python. I am trying to install neuron on a beowulf cluster -- and on a single 64bit machine.. Beowulf has Suse Linux 10 installed and the single 64bit machine debian, the messages are ...

Install nrnpython when Python is in home
Hi, I am using a server where python is not installed and I cannot install python as root. So I have installed python locally in my home directory and it works without any problems. When I want to install neuron, it finds my python version, but it seems to have problems with other standard libraries...

Two instances of Neuron in a Python script
I tried to create a python class, that should create an instance of neuron: Here a very simple example: class neuron(): def __init__(self, tstop): import neuron self.h = neuron.h self.h("tstop = %d"%tstop) n1 = neuron(100) n2 = neuron(500) print n1.h.tstop print n2.h.tstop I expected that ...

Re: ParallelPython and Neuron
On the parallelpython webpage they suggest to do something like this for external programmes to solve the problem with output from different processes, : def test(): from subprocess import Popen, PIPE p = Popen(['ls', '-l'], stdout=PIPE, stderr=PIPE) return p.stdout.read() this gives me indeed the l...

Re: New nrnpython compiling problem
After several days of installing and deinstalling neuron and python, I decided to fully reinstall our server. We have a new fresh ubuntu version now, with up to date python packages.. And Neuron installs without problems... (however still without numpy)
Thank you,
