Thank you, Ted! Indeed the lists are very straightforward in pyhton and much similar to the neuron code. I'll also keep lists in mind when doing something similar in hoc again. About your final comment, I thought of that, and my first thought would be that it should be the same. But I had a second t...

Hi, I'm starting to figure out how to do some things in neuron+python. However, I'm kind of new to python yet and I have a (probably) basic question: How do I translate a code like the following into python? objref GABAinp[N_in], GABApre[N_in], GABAconn[N_in] for ii= 0,N_in-1 { GABAinp[ii] = new Exp...

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...

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...

hmmm...
in case you don't reproduce the error, can you give me any suggestion to debug it?

Thanks a lot for your answer

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. ...

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...

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

Regards

Yes, the file is located in C:\Python27\neuronhome\bin I added the path to the environment variable but it didn't work C:\>path PATH=C:\Program Files\MiKTeX 2.9\miktex\bin\x64;C:\Program (...) ;C:\Program Files \gs\gs8.64\bin;C:\Python27;C:\Python27\neuronhome\bin C:\>python Python 2.7.3 (default, A...

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...

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...

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...

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-...

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 = (10...

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 ...
