The obvious and simple way to plot spikes from a randomspike or spikegen
element is to simply send the state field of the spike generator to a graph
with a PLOT or PLOTSCALE message. This is the method used in the example
Scripts/tutorials/tutorial4.g.

Although this method is often acceptable, it isn't ideal, because a spike
lasts for only a single time step. Therefore, you will have to use the
simulation time step as the time step for plotting (using up a lot of memory
to store points that are mostly zero), or risk missing spikes which fall

The Rallpacks are a set of benchmarks for evaluating neuronal simuators.
The original idea was proposed at the Analysis and Modeling of Neural
Systems meeting in San Francisco in July 1991.

This is an updated version, incorporating suggestions from many people.
We would like to express our appreciation to everyone who helped with the
original ideas and development of the Rallpacks. A partial list includes
Frank Eeckman, Erik De Schutter, John Miller, Michael Hines, Mark Nelson,
Tony Zador, and of course, Wilfrid Rall, who pioneered much of

A perl script which post processes GENESIS Postscript files and reduces their size.

GENESIS user Cengiz Gunay (cgunay at emory dot edu) has contributed the
utility "Gencompress" that can achieve average 10:1 compression ratios for
intracellular voltage traces recorded from GENESIS simulations. It can
operate on files created with the disk_out method.

While the compression is lossless, the data is initially truncated to
16-bit resolution. The FLAC lossless audio codec
(http://flac.sourceforge.net/) is adapted to achieve this performance.

Download one of the following packages:

* gencompress-1.0b.src.tar.gz - Source package for all others

etonic:

This program will ascribe electrotonic lengths to the segments of
a compartmental model. It is to be used with GENESIS .p files
(GENESIS parameter files which describe single cell properties).

dendro:

This file contains the xplot program, a plotting program originally written by Matt Wilson, and modified by Mike Vanier. This program (which is unrelated to the GENESIS object of the same name), may be used to view the results of parameter fits and to compare them with the target data. It also has many other uses. The file xplot.txt describes the many commands and options that can be used with xplot.
