I'm using 7.8.2.

I'll try that soon - I suspect that the issue is related to my extracellular stimulation implementation not playing nice with runtime changes to the morphology of the cell.

Hi, I'm trying to integrate some new functionality into a mountain of legacy code, and this functionality comes from something that's written half in Python and half in HOC, so I'm unsure of what my errors are doing. I'm trying to add a spine to my detailed morphology, and I'm trying to use exactly ...

Still working on this... Moving back to an older version of NEURON didn't remedy the situation but at this point I'd want to be sure that nothing is wrong with Vector.record. Testing my code - calcium accumulation does work - if I ask for cai after the simulation has run, it gives me an answer that ...

It seems that the variable does not exist (or at least doesn't exist when the code goes to look for it). Trying to print it gives me the error "cai suffix not a range variable or section property", or "cai undefined function" if I use your second print line. The parameters of the...

So, I'm checking that our calcium concentration stuff is working properly (we're using a few v-gated Ca channels) with the Ca_DynamicsE2.mod that looks like this: : Dynamics that track inside calcium concentration : modified from Destexhe et al. 1994 NEURON { SUFFIX CaDynamics_E2 USEION ca READ ica ...

That makes sense. I'd shifted to using the indgen method because of another issue, but I found a workaround for that.

Thanks for the quick solution!

I hope this is something minor that I'm missing, but I've noticed a weird discrepancy between my tvec and a voltage vector when I need 1:1 correspondence, but only depending on the time step. The program that I've written has a selectable time step as a parameter: 5us or 25us, and this is set pretty...

Ah, found the problem - their import line was placed in the wrong place relative to the template opening.

Thanks for pointing me in the right direction.

The code is not published in ModelDB; it is posted in the Human Brain Project collaboratory. If it helps, their invocation of the function looks like this: proc load_morphology(/* morphology_dir, morphology_name */) {localobj morph, import, sf, extension strdef morph_path sprint(morph_path, "%s...

Hi, I've been working on an adaptation of a published model, and in attempting to run their code, I get an error in NEURON when their code attempts to load the morphology files, reading "Import3d_Neurolucida3 is not a template". I've been running NEURON fine for months on this machine, and...
