confusing about finitialize() and fadvance()

Hi all, Currently I have been using a mod file ribbon_tiger.mod from modelDB, and I found that when I called finitialize() or fadvance() in hoc file, the content in BREAKPOINT BLOCK would be computed twice, sometimes once. I wonder, in which circumstance, such things (computed twice/once) would happ...

Re: How to transfer Calcium concentrations between two tasks

Many thanks for your checking on the Ribbon Synapse Model! I will take care of them. "First build a model designed for serial execution on a single processor." I have tried the serial implementation, and it works well. The pseudocode is: load_file("nrngui.hoc") create soma_pre create preSyn,preSyn2 ...

Re: How to transfer Calcium concentrations between two tasks

Thanks for your reply! Your advise is so professional! I started by combining a pair of cell and synapse into a single model, and it works well. Next, I would build a network composed by many cells and synapses with some predefined connections. In this situation, I have to consider how to assign the...

Re: How to transfer Calcium concentrations between two tasks

Thanks for your fast reply! First, a question: are the model cell and synapse both implemented with NEURON? Yes, both of them are implemented with NEURON. Actually, I use the ribbon synapse model (accession:50997) provided by ModelDB. And, the cell is defined by myself. It mainly has some calcium ch...

How to transfer Calcium concentrations between two tasks

Dear all, I'm simulating the information transfer (i.e., transferring the Calcium concentration at each time step) from a cell to a ribbon synapse, and the cell and the ribbon synapse are assigned to two cpus respectively. Is there any advice? Thanks! PS: According to the parallelcontext tutorial, t...

Parallel neuron help!

Hi, I'm running some code parallel context on a cluster and meeting a problem. "run_1.hoc" works well without any bugs while "run_2.hoc" dosen't. Could you give me some tips about it? The pseudocode is this ================== run_1.hoc: create soma ... // codes that define a soma create synapse ... ...
