Re: Segmentation violation

Try the following with the 755 sources. Add to your configure CFLAGS='-g' CXXFLAGS='-g' This will cause it to build with optimization turned off. Do you mean to add it as a parameter of the ./configure command? Like in ./configure --prefix=`pwd` --with-iv=/opt/iv-18 CFLAGS='-g' CXXFLAGS='-g' ? (doe...

Re: Segmentation violation

Hi, I'm having problems compiling the latest mercurial repository version. While solivng it, I tried the 7.3-alpha-755 (which I could compile with no problems) and it also crashes. Is there a big difference between those version? Regarding the compilation problem, it happens during make, with the fo...

Segmentation violation

Hi, The following code is giving me a Segmentation violation. It doesn't occur inmediately, but after some simulation time. It can be 50000, 1e5, 2e5 ms and as you can see I'm trying to do a 5e5 ms run. Before anybody asks, there are so many synaptic inputs because they will have different weights. ...

Re: using neuron.h.Graph() through python

Hi, I want to re-float this issue because I'm having it with Ubuntu 12.04 x64, with python 2.7.3 and Neuron 7.2. It also happens with Debian (latest 64bit), python 2.6.6 and neuron 7.2. In both cases I have spyder (2.1.9 in Ubuntu; 2.1.11 in Debian) but it also happens in ipython. I have to say that...

Re: PyNEURON simplify NEURON usage from Python on Windows

OK, with 32bit python it worked at the first try.
So the problem limits to the 64-bit version.

Re: PyNEURON simplify NEURON usage from Python on Windows

Thanks a lot Uri for PyNEURON. I'm trying to set it up. I'm using Python 2.7, 64-bit because I don't care (yet) about compiling (I can compile with the standar 32-bit neuron, right? ... or maybe the compiled dll will not work with the 64 bit python??). Nevertheless, I have not been able to get to ch...

Re: NetStim.interval variable

I wonder if that would work as an ARTIFICIAL_CELL with version 7.2. By the way, 7.2 has now (finally) been released officially. . No, it doesn't. And now there isn't any segmentation violation message, neuron just quits. I really don't like this algorithm for execution during a simulation--requires...

Re: NetStim.interval variable

Well, I found the solution... and a possible bug? It turns out that WATCH doesn't work in an ARTIFICIAL_CELL!! I just changed the process to a POINT_PROCESS, created a mock section to insert it and now it works like a charm! Is this normal? BTW I haven't tried with the last alpha version, I'm workin...

Re: NetStim.interval variable

I did some research and found that the WATCH command may be useful here. Now I have this: INITIAL { if (noise < 0) {noise = 0} if (noise > 1) {noise = 1} if (minRate <=0) {minRate = 0.0001} r_interval = exprand(1) last_event = 0 interval = (1000)*1/(minRate + (maxRate-minRate)*cos(2*3.14159*freq*(t-...

Re: NetStim.interval variable

Thanks a lot for telling me to do what I didn't want to do ;) But I mean it, because it turned out to be easier than I thought... until I got into trouble. I have something like this: INITIAL { r_interval = exprand(1) last_event = 0 } BREAKPOINT { if (t>start && t<start+dur) { interval = (1000)*1/(m...

NetStim.interval variable

Hi, I want to have a NetStim that delivers random pulses but with a variable mean interval. Specifically, I want to have sinusoid form with max=0 and min=20 (or anything resembling that). I have tried by playing a sine vector on Net1.interval, i.e. sinvec.play(&Net1.interval,1,1) But it doesn't work...

Re: Leave neuron running and close the session

Thanks a lot!
I don't know why the subshell trick does not work for me, but if I do
nrngui -nogui myfile.hoc &

and then
disown processID

it's just what I need. The simulation keeps running after logout!
