Is there any way to bifurcate axon?

Hello,
I'm using 'Z. F. Mainen and T. J. Sejnowski (1996)'s model'
https://senselab.med.yale.edu/ModelDB/s ... ls/#tabs-1
I want to bifurcate axon and modify the angle at branching point.

Is there way to do it in GUI tools? or modify the 3D coordinate?

Thank you in advance.

Thanks for providing information.
I changed diameter by using pt3dchange. Thanks!

Re: Find threshold with APCount

Thanks for your kind explanation, Ted. I monitored apc.n by increasing stimulation amplitude to find out the point where apc.n >0 (threshold). And I want to see apc.n of soma, dendrites and axon. I read NEURON book ch.4 and 5. Thanks for your suggestion. But still, there is a problem. I used apc = n...

Find threshold with APCount

Hi, I have some questions about APCount. 1. I read explanation about APCount at programmer's reference. apc = h.APCount(section(x)) Here, section(x) should be written only number? For eaxmple, I write apc=h.APCount(0.5) for see threshold of soma. Can I use section name? 2. If not, How can I know the...

Re: how to deal with "subscript out of range error" in printing out coordinate.

umm.. I found the error! exactly In code, without any function I made or loop, I put only forall {printf("%s: %d \n", secname(), n3d())} Then, the result looks axon did not have its coordination. loading membrane mechanisms from nrnmech.dll Additional mechanisms from files ca.mod cad.mod kca.mod km....

Re: how to deal with "subscript out of range error" in printing out coordinate.

oh, I didn't copy all the result. The error was still happened.
And I found out that when I print secname and nn in front of for loop,

Code: Select all

printf("%s: %d \n", secname(), nn)
The axon part's outcome is zero.

Re: how to deal with "subscript out of range error" in printing out coordinate.

This is code which I put what you said-1.2. for ii = 1, nseg { print ii xr = range.x[ii] printf("one") center_pt.x[0] = xint.x[ii] printf("two") center_pt.x[1] = yint.x[ii] printf("three") center_pt.x[2] = zint.x[ii] printf("four") printf ("\n") //print center_pt //f.printf("%f %f %f \n",center_pt.x...

Re: how to deal with "subscript out of range error" in printing out coordinate.

I got your point. Now I tried to print in a for loop like this. for ii = 1, nseg { xr = range.x[ii] printf("one") print ii center_pt.x[0] = xint.x[ii] printf("two") print ii center_pt.x[1] = yint.x[ii] printf("three") print ii center_pt.x[2] = zint.x[ii] printf("four") print ii printf ("\n") //print...

Re: how to deal with "subscript out of range error" in printing out coordinate.

Thank you for your response, Ted. I had already used print statement and found out the location of the crash. This loop is executed but stops and the error message "subscript out of range error" came out! for ii = 1, nseg { xr = range.x[ii] center_pt.x[0] = xint.x[ii] center_pt.x[1] = yint.x[ii] cen...

how to deal with "subscript out of range error" in printing out coordinate.

Hi, I'm just beginner and undergraduate. I'm using NEURON for my thesis for graduate paper. What i am doing now is that print out coordinate info of each segment into txt.file with using interpxyz.hoc in extracellular_stim_and_rec.zip But the problem is "subscript out of range error". This is a part...
