Using vectors as arguments for pt3dadd
Looking through the documentation for pt3dadd , I see: h.pt3dadd(xvec, yvec, zvec, dvec, sec=section) ... Add the 3d location and diameter point (or points in the second form) at the end of the current pt3d list ... Note: A more object-oriented approach is to use sec.pt3dclear() instead. I am strugg...

Precompiled NEURON 7.5 install on Sierra - not quite successful
Hello, after installing the precompiled NEURON 7.5 app on Mac 10.12.6 Sierra, it looks like installed but the programs don't launch. If I click the nrngui or neurondemo icon in the Applications / NEURON folder, no GUI loads. Only a bash shell loads and just says "-e" and nothing else, and ...

Re: Using Import3D on Mac
Ah, of course! I am working with a different model in my Mac, one that does have a "spines" mod file. I should have realized that right away! Thank you, I'll rename that suffix in the file.

Re: Using Import3D on Mac
I checked the alpha folder and found an installer from July 4, so installed that instead (other version I installed was listed as the most recent general release for Mac on the downloads page). I still get the same error although on a different line number now: oc>/Applications/NEURON-7.5/nrn/x86_64...

Using Import3D on Mac
I am having an issue using Import3D on Mac OS. I just uninstalled and reinstalled NEURON to be sure, and it is still happening. It claims a syntax error (but I didn't see what was erroneous-looking in the read_nlcda3.hoc file near line 1018). $ nrngui NEURON -- VERSION 7.4 (1380:90539e842093) 90539e...

Using pc.broadcast with python
I am having trouble using the pc.broadcast() function correctly in Python. Here is my file mwe.py: from mpi4py import MPI from neuron import h MyString = "oldName" print "The original string is: " + MyString pc = h.ParallelContext() pc.barrier() if int(pc.id()) == 0: MyString=&qu...

Nice tutorials, one minor question
I enjoyed going through the very clear and through neuron+python tutorials. I think there is one line that needs to be updated, or (more likely) it was some sort of user error on my part, being new to python. It is the ball-and-stick network tutorial at: http://neuron.yale.edu/neuron/static/docs/neu...

Set pointer when using mod file that defines pointer
This is just an FYI - my code was erroring out during a call to fcurrent() (as part of the call from finitialize() during the init procedure). It was reporting a segmentation violation and it took me awhile to realize it was due to the use of a mechanism (mod file) that defined and used a couple of ...

Re: NEURON and MATLAB on Mac
The NEURONHOME environment variable is incorrect. If it exists at all, it should be /Applications/NEURON-7.4/nrn/share/nrn That was it, everything works fine after setting NEURONHOME correctly! At any rate, without that variable, what is the result, after a launch, of the hoc function print neuronh...

NEURON and MATLAB on Mac
Hello, I have just started using a Mac with Yosemite 10.10.5, but I am having a little NEURON trouble (or maybe it's actually MATLAB trouble?). I installed NEURON 7.4 and it is working fine. But then when I try to run it from MATLAB 2015a using a system call (which I can do just fine in Linux or Win...

Good call, in my regular code I remembered to initialize, but I had inadvertently removed it from this code. My full code (with al...
