High energy in low frequencies on awake users.
Hello, first of all i am not sure if the term "energy" is the most correct here, so i will clarify that it refers to a normal lecture ^2 at each sample. in the data i am about to show i was trying to analyse the cerebral activity of a subject in different frequency ranges. The way i did th...

Interest of module to show cerebral activity of delimited band frequencies
Hello, i have been developing a couple of modules for BCI2000 which could be of use for someone. One of them involves P300 experiment but instead of trying to predict a character, it predicts a movement reflected in the movement of a little man in a 2d animation. This is more like a curiosity that c...

Operator module configuration. 3 state bar right from each parameter
Hello,
i guess this question has been made before, but i am not able to find it through forums. When we click config in the operator module, we have like 3 selectable states at the right of each parameter. What are this for?
Sorry for the noobish question.

Re: Problem getting SampleRate with MatlabSignalProcessing module
Ouch, you get me again!
I did it this way finally:
str=strjoin(bci_Parameters.SamplingRate);
B = regexp(str,'\d*','Match');
SampleRate= B{1}; %First number
Thanks man.

Re: Problem getting SampleRate with MatlabSignalProcessing module
Sorry i did not mention it before, but i am using a compiled version of BCI2000 of the actual trunk source code. Perhaps it is related to the compilation not being done correctly? I do not think it is an error from the .m code i am using, it must come from BCI2000.

Matlabsignalprocessing module, incoming signal readings
Hello, i am trying to apply my own filter to the signal obtained from BCI2000 with the MatlabSignalProcessing module. However i am not sure own how does the signal income work. Lets assume i have defined BlockSize=3 and ChannelNumber=4. This means that there are 4 channels transmiting and that there...

Re: Building from source code with windows problem
Ok, i have tried something different. I built all the modules needed to run a test using the trunk source code, and seems now it is working. I guess, that for the 3.6 my confusion came from here: http://www.bci2000.org/wiki/index.php/Programming_Howto:Quickstart_Guide: You probably do not need to bu...

Re: Unknown CMake command "QT4_WRAP_CPP".
1) Use the pre-compiled static compilation of QT4 that is downloaded with setting up the build environment of 3.0.5. I do not know if i understand this. You mean not to use external ones? I use external ones because when i use the make VS2010 project files it is not able to download QT libraries. 2...

Re: Building from source code with windows problem
Have built the stuff with the beta version source and it seemed it all was OK (downloaded all necessary software for it). Problem comes when i try to execute a built module (unchanged, so code is not problem) with precompiled ones. I built p3speller, which i run among precompiled signalgenerator and...
