Hello,
how do I record a single cell of a matrix with python?

I know that if I want to record a Vector I can use the following code:
But how do I record from a Matrix, as this does not work

I've found the answer

Hello I am using this code to create a gap junction via a linear mechanism, begintemplate LinearMGap public src, target, g, valid, pr, set_gm, gm, cm objref srcsec, targetsec, cm, gm, y, b, xvec, sl, lm, this, fih strdef tstr proc init(){ g_ = 10 valid_ = 0 cm = new Matrix(2,2,2) gm = new Matrix(2,2...

Hello, I have a network simulation with gap junction, I am using pc.source pc.target for the Gap Junctions. I want to test if my results stay the same when I use linear mechaisem instead of pc.source and pc.target, but it is extremely slow, so I tried to cvode ( is it possible to use cvode and linea...

Ok
all I needed to do is:
nrniv -c "{strdef aa aa=\"123\"}" init.hoc

Hello,
I want to send a string to Neuron when I load it
nrniv init.hoc -c "{strdef aa aa="123"}"

but the problem is that I can not use " inside the " and it does not except '

what can I do?

Thank You.

seems to fix the problem.

Hi Michel Thank You, In python your code does work, But in ipython it does not work In [2]: soma = h.Section() In [3]: zz= h.Impedance() In [4]: h.Impedance[0] Out[4]: <hoc.HocObject at 0x1a0c420> In [5]: zz=None In [6]: _ Out[6]: <hoc.HocObject at 0x1a0c420> In [7]: 1 Out[7]: 1 In [8]: h.Impedance[...

Hello Ted, Thank You, When I run your code, I do manage to delete the Impedance, But when I run the following code from neuron import h soma = h.Section() zz= h.Impedance() h.Impedance[0] zz = None zz= None does not delete the Impedance, Can you try it? It seems that running the line h.Impedance[0] ...

Just add a h.pop_section() after you finish with the section you pushed [push()] and the stack overflow will disappear dend = [h.Section() for i in range(ndend)] for i in dend: i.push() i.connect(soma, 0, 0) i.nseg = npoints i.Ra = 200 i.insert('pas') i.insert('ds') i.e_pas = -70 i.g_pas = 0.00004 h...

Hello, I am trying to delete an Impedance tool in python but I can not manage to do it. in hoc it is very easy objref zz create soma zz = new Impedance() Impedance[0] I get Impedance[0] When I do objref zz Impedance[0] I get nrniv: Object ID doesn't exist: Impedance[0] As expected! -----------------...

Thank You Ted, It works great. If anyone ever needs. This is my solution for recording the current thats going from the soma to the dendrites. (I assume the soma is 1 segment) objref s1, childVolts, childri, somaV childVolts = new List() childri = new Vector() somaV = new Vector() s1 = new SectionLi...

Thank You,
Working Great!

Hi I have what seems to be a weird question. Usually when I want to do multisplit on a model that I am running. I do: Tools-> Parallel Computing -> threads=8 & Multiplit on Refresh and it works. But I can't seems to find the correct commands so that this clicks will be automatically run from the...
