Initialization in heterogeneous network

When creating a network of mixed cell composition (different HH type cells), NEURON will solve the initialization based upon the dynamics of the last cell created (last cell template called). Thus the excitability of other cells is affected, and this small 'corrective' term can be enough to cause an...

szFunctionsObject.left(strSeed,14) is an important step before using sscanf, because I think there's a line break in the string generated by default. Then you can use sscanf(strSeed,"%lf",&intSeed) Technically its a floating point number, but nowhere in your string assignment do you have a decimal ...

I already dynamically assign file names based on changing parameters during the run, but I hope to interactively create folders before each run. I realize I could just hardwire a strfoldername in there and manually assign it before I hit run, but theres a programmer part of me thats frustrated and s...

prompt for string from standard input?

I want to dynamically assign folder names for the data files I spit out after simulations. So far I have used xred to set numerical parameters, but I would like something analogous for strings and havent found it... when used in my hoc file, getstr defaults to the loaded file and tried to grab the n...

randomize() rather than system time seed?

Hello all,

I am attempting to get a true output of random numbers utilizing the c function randomize() in stdlib.h

I must be missing something critical about how neuron compiles everything because I cannot get it to work.

Any ideas?

Wow - an impressive, quick response. I really appreciate it, and will post back if I run into any difficulties. (looks pretty simple written out like that, though)

(without SpikePlot, since I did not use network builder)

Raster plot of spikes in network

I have created a network of biophysical cells (around 50) with a simple ring architecture. Each cell has a single connection to each beside it. I stimulate firing in the soma of one cell, and watch the spikes propogate through the ring using the simple v graph, plotting about 8 different cells throu...
