 +<code> 
 +set xrange [2:5] 
 +set yrange [:5000] 
 +plot 'exc.0.ras' with dots lc -1

 That's a lot of spikes, but the image suggests that there is some synchrony going on at times, but there are also phases of asynchronous firing. Let's zoom in a bit more: That's a lot of spikes, but the image suggests that there is some synchrony going on at times, but there are also phases of asynchronous firing. Let's zoom in a bit more:

-For more sophisticated ways of writing patterns or synfire chain structures into a connectivity matrix, check out the documentation of [[manual:SparseConnection]] and specifically the functions called ''load_patterns'' (see also http://www.fzenke.net/auryn/doxygen/current/classauryn_1_1SparseConnection.html). +For more sophisticated ways of writing patterns or synfire chain structures into a connectivity matrix, check out the documentation of [[manual:SparseConnection]] and specifically the functions called ''load_patterns'' (see also http://fzenke.net/auryn/doxygen/current/classauryn_1_1SparseConnection.html). 
 You can also always load a weight matrix from an external file which have generated using MATLAB or Python. Auryn supports a coordinate based [[http://math.nist.gov/MatrixMarket/|matrix market]] format which allows for the seamless exchange of weight matrices with external tools (see [[manual:wmat|matrix format]]). You can also always load a weight matrix from an external file which have generated using MATLAB or Python.
