Thanks for your reply. I inherited this model from my predecessor. The synaptic mechanism which I am talking about though is a published one. The title is Synapse C=O gating scheme. Published in: Sergio M. Solinas, Lia Forti, Elisabetta Cesana, Jonathan Mapelli, Erik De Schutter and Egidio D`Angelo ...

Thank you very much for your reply. In my model the post synaptic cell has jus one compartment(soma). All the incoming connections are excitatory and they have similar properties. The synapse is a separate point process written as mod file. Here are my observations. 1. When i connect the incoming co...

I have a small doubt regarding parallel implementation of network model. I was going through this paper http://www.neuron.yale.edu/neuron/static/papers/jnm/parallelizing_models_jnm2008.pdf For example pls consider this scenario. Suppose we have 'n' incoming connections to a cell and we need to conne...

Thank you very much..

Is there anyway to send data from host to another during generating network connectivity ?

For example if the number of process = 4, if have a list(of vectors) generated in host 0 . I want this list to be used by cells in host 1, host 2, host 3. Is there anyway to do this ?

Thanks in advance

Hines, Thank you very much for your reply. I did scale down the size of my model to half its size. I get the same error using python wrapper but not using hoc. But if i reduce beyond this value, the model works fine using both the python wrapper and hoc. Is there any way to get rid of this error ? t...

I have a model which has a set of hoc and mod files. I declare the methodology for running my model as given below. 1.Using hoc -- just run using a hoc file 2.using Python - write a python file to call all the hoc files using h object. eg h.load_file("init.hoc") and run it When i run using...

I have a large network model. When i run it using pyNEURON i get a lot of memory problems. Given below is an example. nrniv(63134) malloc: *** mmap(size=34816000) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug /Users/shyam/neuronlatest/nrn...

Hi Ted, I would be happy if you could answer this another small question of mine. As in the past i am working with COBA cell model in a network. With reference to Spikeout.mod, What will happen if another spike arrives as input when the neuron is in refractory state ? Will there be a response in mem...

Dear Ted,

It works with NEURON 7.2. thank you.

Dear Ted,

For all the models (including mine) i was able to generate the mcomplex.dat file. But when i try to run using mpiexec it creates the error which i quoted before. Any way i will do what u said and contact you shortly.

Thanks.

Dear Ted,

I think its NEURON 7.1. Is that you want to know. When i click nrngui i get a white window which has the following lines.

I should also mention that the hoc name of a GLOBAL parameter has the general form parametername_mechanismname regardless of whether the mechanism is a density mechanism or a point process This answers my question. I saw an assignment statement like this. But i never knew it was for thresh and vref...

Hi, I have a complex morphological cell which takes a longer tome to run. So i wanted to use multi split method of parallelization. I was going through this post which was very informative. http://www.neuron.yale.edu/phpBB/viewtopic.php?t=2018 So i followed the steps which was mentioned by Ted. Howe...

Thank you Ted for all your explanative replies..
