Re: Strange problem during fitting process: is it a bug of n
Actually no. As I told you before I found another temporary solution for my problem because I had to send the revision of my article as soon as possible. Still, I think there is sth wrong with NMODL. I delayed sending my model to you because I wanted to write a simple test code for you but I could n...

Strange problem during fitting process: is it a bug of nrn?
I have a mechanism in my model which calculates amplitude of EPSPs for me. I have non-uniform model so I have to initialize my model to the steady state (when t<0). My synapse become active at t = 10. this is my mechanism. NEURON { SUFFIX vmax RANGE vm, tm, vrest, amp } ASSIGNED { v (millivolt) vm (...

Re: How to find the sensitivity of the fitting on parameters
Is there a solution for the above problem? Please, tell me if there is not.
Besides, latest alpha version of neuron has problem compiling in windows:

How to find the sensitivity of the fitting on parameters?
Hi
I'm trying to publish an article in which I have used multirunfitter tool of NEURON. One of my reviewers has asked me to show sensitivities of the fitting on parameters. How can I do that?

Re: Initializing potassium concentration in hoc
ek is merely a parameter whose value can be assigned with a simple hoc statement like ek = -90. Thank you for the tip. I didn't know ek can be a parameter itself. There is no need to calculate ek from the Nernst equation at initialization or on every fadvance() if there is no mechanism that WRITEs ...

Re: Initializing potassium concentration in hoc
When I changed the ion_style() to ion_style("k_ion", 2, 2, 1, 1, 1) everything worked fine. Now my question is 1. what is the difference between assigned or state type of c_style (or e_style)? I have a model of M-type potassium current with the following USEION statement in the NEURON bloc...

Re: Probable bug in IClamp mechanism
I was thinking about this all the day. I think I found the solution. the init code should change in this part:
excuse me if I asked this stupid question. I should be more careful.
Code: Select all
while (t < 0) {
fadvance()
}

Re: 2 fitness generators in multirun fitter
Thanks a lot Ted an Raj.
Today I find some time to work on these ideas. Ted's idea was easier to implement and it worked for me.
Thanks a lot again.
