I just had this issue crop up again as well. Good catch with the Python version number. Like you, with Python 3.12 I could not import neuron. But then I reverted to Python 3.9, and this solved the problem. Are you able to simply go back to an earlier Python version, at least until they update NEURON...

I found the answer to my second question. In section 10.1.7.5 of The NEURON Book (describing the NET_RECEIVE block of a mod file), it states, "every event has an implicit argument called flag, the value of which is automatically 0 for an external event." It would still be very nice if some...

I am attempting to incorporate STDP in a network model, and I am starting with a two-neuron network in which I want to incorporate a very simple STDP model. Reading around, I see various references to a mod file for STDP written ages ago by Michael Hines (e.g., https://www.neuron.yale.edu/phpbb/view...

I am just starting out using artificial cells, so I found this post very helpful. In case anyone is interested, below is a very basic program that implements a version of Ted's pseudocode in Python. Note that I did not have to update intfire1.mod, as it appears to already have the code for calculati...

Thanks, Ted, that makes sense that this would be useful for the purposes of a GUI. Maybe Robert can help with the other question...

I decided I couldn't live with myself if I didn't try to implement the more acceptable approach you suggested (passing all variables as arguments, and then returning them). However, I'm running into some trouble with syntax. I can change spikehappened to the following: def spikehappened(tsp, count, ...

Okay, I guess I'll just be more careful in using SaveState. And this actually cleared up my other question, too. Thanks, Ted!

I am having a few issues using h.SaveState(). First, I've found that switching the order of recording vector statements results in the program crashing when trying to restore. Here is my code (which the BallandStick class from https://neuron.yale.edu/neuron/docs/ball-and-stick-model-part-1 ), which ...

Thanks, Ted, that worked like a charm! I hadn't thought to use global variables, and that is a perfectly acceptable solution for my purposes. Appreciate the help.

I got this working, but the code is terribly ugly, and I'd appreciate any insight into how to clean it up. First, I defined a very simple mechanism with the following mod file: NEURON { SUFFIX sp RANGE spike_count, tnow, isinow, isiprev } ASSIGNED { spike_count tnow isinow isiprev } In the Cell temp...

If I change the function to FInitializeHandler to def set_spike_count(spike_count=0): print('set_spike_count: spike_count = %d' % spike_count) and then replace nc.record(spike_callback) with spike_count = 0 nc.record((spike_callback, spike_count)) then the program runs without error. But it doesn't ...

Thanks for the help, Ted. I have to admit I don't understand FInitializeHandler very well even after reading its documentation page. In particular, I can't figure out how to initialize a variable 'spike_count' that is associated with the NetCon, and then connect the 'spike_count' variable defined fo...

I am simulating a single neuron with adaptation currents, and I would like to run a simulation until the most recent inter-spike interval differs from the second-most-recent inter-spike interval by less than some prescribed threshold. I have basic code that records spike times, so I'm wondering abou...

That did it...thank you very much for all your help!

Thanks, that makes sense. Also, I stumbled on one more issue: my mod files are now compiling fine using the Linux distribution, but in Windows I receive the following error message: Ih.c:7:10: fatal error: scoplib_ansi.h: No such file or directory 7 | #include "scoplib_ansi.h" | ^~~~~~~~~~...
