Re: The effect of changed dt and steps_per_ms
Thanks for your kind explanation. Also, I read the article you recommended. However, I still have a question. As you mentioned, The error of of the approximate solution is generally reduced if time and space are chopped into smaller pieces. ... f the spatial or temporal discretization is too fine, r...

The effect of changed dt and steps_per_ms
Hello, I'm a graduate student who studied with NEURON. I conducted extracellular stimulation to anatomically realistic models via the code written by Ted, and investigated electric field thresholds (through apc.n, I checked somatic membrane polarized over 0 or not). However, there was difference in ...

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.

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 k...

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,
The axon part's outcome is zero.
And I found out that when I print secname and nn in front of for loop,
Code: Select all

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") //pr...

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("fo...

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...
