Well, it relies on the main script structure... Organize your functions and variables such that the total number of task is: #tasks = #repetitions . #values to be tested i use this simple code: /////////////////////////////////////////////////////////////////// n // Number of tasks N // Number of re...

Another Kind of parallelisation

Hi everyone, A frequency parameter for my stimulation is increased at each turn of a loop, 50 frequencies are tested at each run. I've parallelised the process such that n trials can be performed simultaneously, for a statistical analysis. (i use the ParallelNetManager) Is there any easy way to para...

Loglog

Hello everyone,

Does anyone know how to plot a vector with a logarithmic scale, similarly as would do the matlab loglog function?

I haven't found any clue in the documentation neither in the forum.

Any ideas are welcome =)

Thank you Ted for answering,

I guess i supposed the cast to be automatic.
For those who would like to prevent this error, you can cast your vector size by using the simple command "int".

i.e: N = int( ... )
vec = new Vector(N)

Very best,

=)

Vector size and declaration

Hi everyone, i've a reproduced in a simple script a problem that occured in a complex one. Basicaly, i declare 2 vectors of the size Number_Of_Loops. Then there is a for_loop, I fill in the vectors at every turn of the loop. This is working generally well but, for some parameters it freaks out! The ...

OK! The way to make it works is to correctly implement the error function: This code works with the both fitting procedures ++ v ////////////////////////////////////// objref gg, dat, indep, vac, fitsine, carrier, carrier2 gg = new Graph() dat = new Vector(5) //Contains the Data to fit dat.x[0] = 0....

Fit praxis

Hi everyone, I'm trying to get use with the fitting procedures available with NEURON. I've troubles with the fit_praxis function that i didn't managed to solve despite the documentation and the other topic posted by jennap. Here is a simple code doing the fitting of 5 points with a sinusoidal functi...

I'm using the standard run system, and indeed, the data processing should normally occurs once the simulation has ended.

I'll go through the documentation you send me.

Thanks for your fast response =)

Displaying the membran cell potential

It seems this is the source of the problem. The recording duration is really fast without displaying.

The previous recording has been performed within 2 minutes!

Simulation duration

Hi everyone, i have observed a quiet annoying process while recording spikes times of a single cell: the time dilates during the simualtion. I explain: the first 10 seconds lasts 12s seconds 20 to 30 lasts 20s seconds 40 to 50 lasts 40s The times spike are put into a vector which is processed into a...
