Question about P3Speller Classification
Hi all, I have always had a big doubt about the methodology used for ERP classification in BCI2000, specifically for P3Speller tasks, but now it is really important to me know how it works. When I accessed to "Association.cpp" (MostLikelyTarget function) and checked how the system determin...

P300 Speller - Spatial Filter Issue
Hello everyone, I have developed several BCI applications based on the P3Speller oddball task in the past. This is the first time I am using the new BCI2000 3.6 version, and I noticed that you made several changes here. I think that one, in particular, is likely to be a bug. The problem lies on the ...

Newbie question: accessing parameters
Hi, In my custom application, I write the SWLDA scores into a file when the P3Speller flashes finish. To do so, I modified "Association.cpp" and "Association.h" files. However, the output file was located in a rigid filepath (e.g., "../data/SWLDAscores.txt"). Now I want...

Re: BCI2000 v3.6 beta test
Hi, I had suffered the "bundled applications error" documented here: http://www.bci2000.org/tracproj/ticket/180; in a Windows 8.1 machine with IDE Visual Studio 2012 and BCI2000 release 5158. Although BCI2000 v3.6 beta version "BCI2000.x64.bundled" binaries give the same error ag...

Re: Bundled .exe Applications Error
Thank you for your quick reply. I am going to try to disable those app bundles with the described workaround. I would like to test the beta phase, but I would need a BCI2000 v3.6 Beta Source Code (i.e., the "build" folder), because actually I am a developer, so I do not need the given bina...

Bundled .exe Applications Error
Hello everybody, I have developed BCI applications with previous BCI2000 releases, but I am experiencing problems with the new ones running them in Windows 8.1. I have downloaded via SVN the last BCI200 version (release 5158), and I have been able to successfully compile the source code with CMake 3...

Re: Sending a combination of keystrokes
I have been searching about this and i have found that a combination of keystrokes can be sent by HOTKEYS (IShellLink::GetHotKey).
CTRL hotkey is 0x0200 and 'B' key is 0x0042, so the combination would be: CTRL+B=0x0242 (or 578 in decimal). But it does not work in the KeyStroke Expression.

Sending a combination of keystrokes
Hi, I am using the KeystrokeExpression in order to transform P3Speller selections into keystrokes. My expression detects if the SelectedRow state is greater or equal than 2 and send a 'b' or an 'i' depending on the result. But I have a problem when I want to send a combination of keystrokes like &qu...
