Hi Ted Yes, I think I'm doing it the right way, sorry for not giving more details about what I was doing. Actually I was trying the first option, Print/Postscript , after selecting a window and seeing it appear in the page layout and adjusting its size and position. BTW I could successfully do the e...

Hi, Postscript export is giving me an empty file, and I get the messagse oc>system("command")"sed" no se reconoce como un comando interno o externo, programa o archivo por lotes ejecutable. which roughly translates as system("command")"sed" not recognized as a...

the export command is a UNIX command not working on WIN Exactly!! As I told you, you have to open a bash command window (A *NIX-like environment that gets installed with neuron, part of MinGW), issue the export commands and run pyhton (or spyder!) from there; then you will be able to import neuron....

For environment variable in WIN environment variable editor I used NEURONHOME C:\nrn73w64 PYTHONPATH C:\nrn73w64\lib\python You don't have to do it in the Windows environment variables, instead (or in addition to??) you have to do export NEURONHOME /c/nrn73w64 export PYTHONPATH /c/nrn73w64/lib/pyth...

Thanks!

Hi, The as_numpy() function is giving an error: >>> from neuron import h Unable to load 'mpich2nemesis.dll', error 126 NEURON -- Release 7.3 (901:c736db45853d) 2013-06-29 Duke, Yale, and the BlueBrain Project -- Copyright 1984-2013 See http://www.neuron.yale.edu/neuron/credits >>> vec=h.Vector(10) >...

It's working!!
The best part is that I can even call spyder from the bash shell and then import neuron. Mods compiled with mknrndll are correctly imported also. I haven't actually run any simulation yet, but be sure that I'll let you know if anything doesnt go as expected.

Thanks a lot.

Well, I'm still not getting it. With Neuron 7.3 x64, I get the 'no module named hoc' error, unless I add c:\nrn73x64\bin64 to PYTHONPATH as well. It also works to copy hoc.pyd to the c:\nrn73x64\lib\python\neuron folder. In either case, however I get the following error: 'DLL load error: hoc.pyd is ...

you can extend Python xy with NEURON (but not use any interviews gui) if you install http://www.neuron.yale.edu/ftp/neuron/versions/v7.3/nrn-7.3.x86_64-w64-mingw32-setup.exe and then set the environment variables mentioned in the 16May2012 12:21 post above. Well, I took some time before trying (act...

Thanks for the answer!
Yes, it's easy to make a vector; I just wanted to know if the behavior was 'bug or feature'.

Hi, The following simple code is giving me a Segmentation fault at init(): load_file("nrngui.hoc") create soma access soma insert hh objref celsiusvec,timevec celsiusvec=new Vector(10) celsiusvec.fill(20) for (i=0;i<=8;i=i+2) {celsiusvec.x[i]=18} tstop = celsiusvec.size()*1000 celsiusvec.p...

Oh, I can see... and I fully understand!
But this is about the GUI, right?
What about version 7.3? Is there anything I can do about it? (compile, etc.?)

Hi, I could make it work under Win 8 x64, with the latest Python x,y. However there are two issues: 1) The Neuron version installed by pip is 7.2, not (yet?) 7.3. I really need 7.3 because I'm making use of the as_numpy() function. Will it be updated anytime? Is there anything I can do to help? 2) G...

You are right.
Thanks!

EDIT: And it's waaay much faster!!!

Solved by adding That worked for me.

Also, the behavior of the plot is better if I use In this way the time scale will adjust automatically as tstop is changed.
