Re: h.finitialize() fails with a hocobj call error
Running the model requires the 8.swc file. Please send that to michael.hines@yale.edu as a an attachment. Or zip file if there are are other files needed to run the model.

Re: NEURON 7.6.7 - Permission denied. Python not available.
https://github.com/chlubba/PyPNS/pull/6 has been merged to master. The expectation is that all versions of NEURON will now produce the same results modulo nondeterministic use of random variables.

Re: NEURON 7.6.7 - Permission denied. Python not available.
When I use NEURON-8.1.0 with python3.9 on my linux desktop and install PyPNS from github and run python -i test.py I get (pypns-39) hines@hines-t7500:~/tmp/pypns$ python -i test.py 1 Creating axon 0 Myelinated fiber diameter: [0.97982345] Number of segments for myelinated axon: 2208 Starting simulat...

Re: NEURON 7.6.7 - Permission denied. Python not available.
Yes, I got this message but for version 8.0. NEURON -- VERSION 7.6.7-3-gef035d9b 7.6 (ef035d9b) 2019-04-28 That confuses me.I can't reconcile the "version 8.0" with the 7.6.7 banner. Anyway, I suppose it is potentially possible for me to rebuild a version of 7.6.7 that has a python 3.8 in...

Re: NEURON 7.6.7 - Permission denied. Python not available.
i.e. nrn-7.6.7.w64-mingw-py-37-36-35-27-setup.exe
Sorry, it was staring me in the face the whole time. That installer does not have an interface dll for Python3.8

Re: NEURON 7.6.7 - Permission denied. Python not available.
When you temporarily installed the most recent version of NEURON, were you able to successfully launch
nrniv -python
from a command prompt?
nrniv -python

Re: NEURON 7.6.7 - Permission denied. Python not available.
The syntax for set statements in a command prompt terminal does not allow spaces surrounding the '=' . I don't know how they crept into the code fragment above. Please try again in a command prompt the following set NRN_PYTHONHOME=C:/Users/amalu/anaconda3 set NRN_PYLIB=C:/Users/amalu/anaconda3/pytho...

Re: NEURON 7.6.7 - Permission denied. Python not available.
try the following. Be careful about the distinction between / and \ Start a windows command line terminal and type nrniv quit() I just want to verify that you can launch nrniv but also get the error. Then set NRN_PYTHONHOME = C:/Users/amalu/anaconda3 set NRN_PYLIB = C:/Users/amalu/anaconda3/python38...

Re: NEURON 7.6.7 - Permission denied. Python not available.
If you use the bash terminal that is installed with NEURON, it suffices to copy/paste into that terminal window export NRN_PYTHONHOME = "C:/Users/amalu/anaconda3" export NRN_PYLIB = "C:/Users/amalu/anaconda3/python38.dll" And, by the way none of this is needed if you launch pytho...

Re: NEURON 7.6.7 - Permission denied. Python not available.
nrnpyenv.sh has changed a bit over the past few years as it occasionally needs tweaking when new python installations become available. I suggest the experiment of replacing c:\nrn\bin\nrnpyenv.sh with https://github.com/neuronsimulator/nrn/blob/master/bin/nrnpyenv.sh The purpose of the script is to...

Re: After updating to MacOS 12.3 Monterey
Perhaps you have not installed the xcode command line tools. From a Terminal, type xcode-select --install and see if that fixes the problem. Although I'm curious about why you had a import error when importing neuron after a package install. No need to pursue that now since your pip install fixed th...

Re: MacOS 12.3; Application "Terminal" can't be opened. -1703
I just upgraded to 12.3 and am experiencing the same issue when double clicking the nrngui or neurondemo icon. I'll try to diagnose and fix this. Meanwhile, a possible work around is to manually start a terminal window and launch neurondemo or nrngui from there by typing those names into the termina...

Re: Running tests after building from source
The ctest -VV command could not find tests. I'm not seeing a problem with that (when launched from the build folder). It verbosely executed all tests. Not sure what went wrong in your case. Please copy the error message here. test_bbss.py produced errors about HocObject no attribute 'Follower'. Cha...
