Re: spectralSize and spectralStep

I'm not sure what you mean by "baseline recording settings," but in case you are referring to the parameters for the initial mu session, there is no online processing performed for these data. Thus, OfflineAnalysis does not read its spectralSize and spectralStep parameters from the data f...

spectralSize and spectralStep

Hello all, I've been working with the OfflineAnalysis tool for a while now, but I want to make sure I understand how the data is processed exactly. If anyone has a good (read as 'detailed') explanation of this process, would you mind explaining it to me? Also, I've found that there are 2 parameters ...

EEGlab import - Expression or statement is incorrect

I followed the steps to install EEGLAB import and I got the following error upon trying to load a .dat file.

Expression or statement is incorrect--possibly unbalanced (, {, or [.

I was using the latest version of BCI2000, I have used an older version of EEGLAB import and I didn't have this problem.

CursorTask Render Setting Changes Cursor Movement

Hello, To test the CursorTask application I've been using the SignalGenerator to create a 10Hz signal at 100uV. I've setup the Classifier such that Ch1 at 10Hz will make the cursor move to the left (assign a negative weight to it). However, the cursor seems to move to the left if I set the Rendering...

SpatialFilter CAR

Hello,

I want to use the CAR with the SpatialFilter toolbox. Does this mean I must set up a filter matrix, or is it sufficient to fill in the SpatialFilterCAROutput box?

Thanks

Biosemi external channels

I'm trying to collect data from the 8 external channels as well as 128 electrodes (A - D). How might I go about this? It doesn't seem to work if I just add more channels to the 'channels' parameter in the SignalSource tab.

SigfriedSigProc - ElectrodeCondition parameter

I am a bit confused on how to set up the ElectrodeCondition parameter for SigfriedSigProc. I'm interested in displaying real-time data only.

Thanks.

Biosemi data collection problems

Hello everyone, I am using a Biosemi system with the SigfriedSigProc filtering application for real-time brain mapping. However, about 20 seconds into a session this will happen. Another picture a few seconds later. I have SourceFilter included in the Biosemi application and I am applying a high pas...

Re: Unhandled win32 exception occurred in BioSemi2.exe

Since the .exe does not include the source code, I followed the steps above using the biosemi source code. This time I did not get an error.

What I've learned from this: use C++Builder instead of Visual Studio.

Thanks for your help.

Re: Unhandled win32 exception occurred in BioSemi2.exe

Yep, I get the same error.

An unhandled win32 exception occurred in Biosemi2.exe [3864]

However, the biosemi download link provided by gschalk, in this thread: http://www.bci2000.org/phpbb/viewtopic. ... it=biosemi
seems to work just fine.

SigfriedSigProc

According to the link below, there should be a "SigfriedSigProc.mak", however, there is not.

Does anyone know how to build this module?

Unhandled win32 exception occurred in BioSemi2.exe

I'm new to BCI2000. From the title, I'm using BioSemi as my signal source. I compiled it following the instructions from this page, using Visio Express 2010: http://www.bci2000.org/wiki/index.php/Programming_Howto:Building_BCI2000 However, when I try using it in conjunction with P3SignalProcessing a...
