This free program allows users to download, experiment with, and tweak, the example circuits posted on this site. Users can even create their own realistic, action potential using, neural circuits but they cannot save any creation to disk (that requires the full version which will sell for $39.95 and which will be available shortly).
The program will make a directory called Soft State Magic into which it will install the program. This program requires your computer to be running Windows XP or Windows Vista, have the Net 2.0 framework installed, and have the graphics library called DirectX 9.0c installed. The installer checks for the needed .NET framework before installing the Brain Sim Circuit Software. You can find these at http://microsoft.com/downloads. IMPORTANT: If you have any problems getting the program to run you need to install the latest DirectX (graphics card software) from Microsoft here: http://www.microsoft.com/downloads/d...displaylang=en Edit (June 20, 2008) Uploaded version 1.0.0.2 which corrects some loading files issues. Edit (June 20, 2008) Uploaded version 1.0.0.3 which corrects even more loading file issues by tightening up the error detection. Edit (June 23, 2008) Uploaded version 1.0.0.4 which fixes the brain circuit loading error. Edit (September 16, 2008) Changed the requirement to .NET 2.0 instead of .NET 2.0 and greater. |

Re: Brain Circuit Simulation Demo/Viewer
The program won't work for me, it will simply start and terminate immediately without opening any window or giving an error message. I have Winxp (German), .Net 3.0 and DirectX 9.0c. Monitoring the program start via Sysinternals Process Monitor didn't really show me what the problem is, sadly. Maybe you could make it show error/debug messages instead of simply terminating?

Re: Brain Circuit Simulation Demo/Viewer
That sounds like a localization error in the software (by default code is set to the "culture" of ones computer. In this case my computer here in the States and it will not run in other "cultures" unless explicit steps are taken to allow that). I thought I had accounted for that but obviously not.
Also true I should have put in an error catching routine for that. I will look at that today. |

Re: Brain Circuit Simulation Demo/Viewer
Hah, I found the error, thanks to Process Monitor (praise to Sysinternals!). Process Monitor showed me that your program was looking for d3dx9_36.dll without success, and I found out that there was only d3dx9_35.dll and lower present on my system, so I downloaded the latest Directx redist and that added the dll. Seems like there still are newer versions of DX9.0c since I already had it installed for some games. It might be a good idea to point out to users that they will really need the absolute latest version of DX9.0c.
Edit: I tried the new version after renaming the dll to artificially create the old error and it would still instantly terminate as expected.. in any way, localization wasn't the problem. |

Re: Brain Circuit Simulation Demo/Viewer
Interesting, I am not sure how that got beyond the installer. Another bug to track down and I need to try and catch that 3-D engine initialization error also. I just noticed I have not done any error catching involving the 3-D engine.
 Thanks for tracing that down. |

Re: Brain Circuit Simulation Demo/Viewer
When you download a circuit example you have the program open the folder within the unzipped folder (the one with the number on the end). The reason you have to open a folder is that signal generators and neurons are different files. In the future I expect different files will be needed to define the virtual world for testing neural circuits in a realistic environment.
