Re: Error: stack too deep

It works! Thanks!

Where can I find some info about the command line options of nrngui and their meanings?

Re: Error: stack too deep

I don't understand. experiment.hoc is a text file that contains hoc statements? How can typing the name of a hoc file at the command line do anything useful? experiment.hoc is a text file which contains hoc statements, as you said. Once exectuted, It loads the model and runs the simulations. In oth...

Re: Error: stack too deep

It's a command line option, like command line options that other Linux programs have. If you want to specify a different value from NEURON's default, for example 2000, then instead of nrngui foo.hoc type nrngui -NSTACK 2000 foo.hoc I meet some problems when I want to run my simulation using the com...

Re: Error: stack too deep

Is it one of the interpreter options? How can I check the current size of stack? The default value is 1000, but I want to check if I really change it. Where I can find info about this argument? I had a look on "quick reference" and NEURON book, but nothing... I don't understand if my progr...

Error: stack too deep

Hello folks,

I am running my model several times (for statistical significance), but always after the 6th run I get the error:

Stack too deep. Increase with -NSTACK stacksize option

I don't understand which problem causes this error and how to solve it.
Could someone jelp me?
Thanks a lot!

Re: Instantaneous firing rate

So you need a spike-triggered synaptic transmission mechanism that has use-dependent depression, and recovery from depression has a monoexponential time course whose time constant depends on the interval between the two most recent presynaptic spikes. Do you already have a spike-triggered synaptic ...

Instantaneous firing rate

What is your operational definition of "instantaneous firing rate"? I need an inst.firing rate defined as following: freq = 1 / ISI where the inter-spike interval (ISI) is defined by the spike time (NetStim event) minus the spike time of the previous event ISI = t2 - t1 Can you be more sp...

Instantaneous firing rate

Thanks for your reply. First a question: which of the following do you want? 1. A mechanism that is inserted into a presynaptic compartment, and is affected by the firing rate in that compartment, but is not really part of the synaptic machinery. 2. A synaptic transmission mechanism that is affected...

Instantaneous firing rate

Dear all, I am working on a single cell model which receives synaptic inputs from netstim. I need to add a presynaptic mechanism which depends on the instantaneous firing rate. With a regular input (nestim.noise = 0), the inst. firing rate is simply neststim.interval, but with an irregular input (no...

Multiple Run Fitter options

Dear all, I have read the tutorial “Using NEURON’s Optimization Tools” but I still don’t have clear some options such as “append the path to the savepoath.fit”, “|| Optimize” and “# quad forms before return”. Is there another tutorial I can read? How can I fix the numbers of runs before stopping the...

Didactic models

Thanks for your replay and your useful suggestions. Actually I didn't mention an important point. For a new project in my lab, I am going to use a model (already posted in modelDB) and modify it for our purposes. As I said I am studying tutorials and the neuron book, but I have still problems readin...

Didactic models

Hello folk, I am a beginner in programming and Neuron. I started with some tutorials found here and now I am reading the Neuron Book. I think that the next step could be reading and understand some models, but the models I found in tutorials are too simple and the ones in the modelDB are still too c...
