This is the reference manual for GENESIS version 2.3. As there will be continuing updates and additions to the manual, please be sure that you have the most recent version. Information about the latest version of GENESIS and its documentation may be found on the GENESIS WWW site, http://www.genesis-sim.org/GENESIS/.
The help files in the on-line version (in the genesis/Docs
directory) may be viewed with the GENESIS command "
help topic |
more", where "topic" is the name of a file with the extension
".txt". As they are ASCII files, they may also be printed. In
order to view the documentation in these help files in the
recommended order, type ``
help CONTENTS | more'', or print out
the file ``CONTENTS.txt''.
Beginning with GENESIS 2.0.2, we have also incorporated these files into a hypertext documentation system, which may be viewed with a web browser. The HTML hypertext documentation for GENESIS is in a separate directory, genesis/Hyperdoc. The main file is "Manual.html", and there is a README file giving further information.
Some of the new features in GENESIS 2 are not yet documented here.
You may find a brief summary of these and the significant differences
from previous versions of GENESIS under
If there is no documentation for a particular GENESIS command, give
the name of the command followed by ``
-usage'' from within
GENESIS. Likewise, you may obtain a brief description of a GENESIS
object by typing ``showobject'' followed by the name of the object.
The GENESIS Reference Manual is primarily a summary of the syntax used by the GENESIS Script Language Interpreter, the commands which it recognizes, and of the main GENESIS ``objects'' which are available for constructing simulations. However, it will not tell you very much about the use of GENESIS for the construction of neural simulations. For a ``Users guide'' to GENESIS, we recommend ``The Book of GENESIS'', by James M. Bower and David Beeman, Springer-Verlag (1998). The free Internet Edition is available at http://www.genesis-sim.org/GENESIS/bog/bog.html.
Part II of this book provides a detailed tutorial guide to the process of constructing neural simulations with GENESIS. These tutorials progress from the construction of simple cell models to detailed cell and network models with a sophisticated XODUS interface. For further information, see The Book of GENESIS.
The GENESIS/XODUS documentation (Revelations) is contained within the genesis/Doc and genesis/man directories. The former contains the main GENESIS documentation, and the latter contains UNIX man pages for external utilities (such as convert), which are used with GENESIS. The README file in the Doc directory explains the use of the on-line help facility.
The genesis/Scripts directory has a README file which describes the the database of simulations and its library of channels and other simulation components (Numbers).
In addition to containing the C source code for GENESIS, the genesis/src directory contains a README file and a commented Makefile. These files (Leviticus) give detailed instructions for the compilation and installation of GENESIS. They also suggest ways to avoid common mistakes when installing GENESIS. (For example, an incorrect pathname to a system library is an abomination to the compiler.) We still haven't thought of a good excuse to call something Deuteronomy, but are working on it.
After installing GENESIS, start the simulator with the command ``genesis''. (In some cases, you may wish to use one of the command options described in the documentation for genesis.) After experimenting with the on-line help, your first step should be to try out one of the demonstrations or tutorials in the Scripts directory, following the directions in its README file. You may create your own simulations by modifying these simulation scripts.
