Re: Accessing Pointers instantiated through Python

Thanks for the clarification Robert, perhaps then I'm looking in the wrong place -- instead of querying the pointer for targets and sources it sounds like I should instead refer to the double pointers that are being assigned The equal sign notation for assigning pointers is much clearer, thanks for ...

Re: Accessing Pointers instantiated through Python

Thanks Ted, my intentions for programmatically accessing pointers are primarily for model inspection and documentation purposes -- I want to keep track of all variables that are being targeted as well as their sources The context is that I've built on previous work to develop a set of helper Python ...

Re: Accessing Pointers instantiated through Python

Curious if the moderators can point me in a direction here, or advise on if it is more appropriate to move this post to another part of the forum

Feedback would be greatly appreciated

Accessing Pointers instantiated through Python

Dear forum, I'm looking to programmatically access NEURON Pointers that were instantiated using "h.setpointer" in Python Where do Pointers constructed by "h.setpointer" live, and what's the best way to access them? For example, let's say I have two sections (secA and secB) that a...

Re: POINTER is not thread safe

Ah, is the compilation output giving any clues about why it might be stuck?

Yes, I think it's fair to ignore the thread-safe warning if there isn't plans to use multi-threading

Sure, we can take a look at the equations to see if they match up - I'll share my email with you in a direct message

Re: POINTER is not thread safe

Hi Alexandra, The first error of "Use of POINTER is not thread-safe" is due to the use of Pointers "vpre" and "vpost", and is only a concern when enabling multi-threaded simulations. If multi-threading is not being used, then this error can be safely ignored and nrnivmo...

Re: Kernel dies in Jupyter notebook when attempting to import NEURON

The mod files themselves had different names but shared the same SUFFIX.
NEURON gave the appropriate error message when I tried to import NEURON in python from the command line.
