Re: BCI2000 build code errors, gNautilus

Hi, and welcome to the BCI2000 forum! CMake is not deleting your entry but moves it below the CMAKE group. You will find it when expanding that group. The errors related to building icons are irrelevant. They occur on some systems due to concurrent access to files (CMake does not offer any synchroni...

Re: Error using load_bcidat in MATLAB

This is a Matlab exception that indicates that no memory could be allocated for the signal data in your file. Within Matlab, a file requires a little bit more memory than its size on disk. With a 32 bit version of Matlab, the maximum file size that load_bcidat() can read is about 1.5GB. You may get ...

Re: BCI2000-based softerware development

Hi,

the BCI2000 GUI is not a library. If you want to write your own GUI on top of BCI2000, I suggest you start out with the Operator (OperatorQt) and modify it by adding or removing elements as you see fit.

Re: Need help connecting via LSL

It seems that the source module is unable to make a connection to the OpenBCI stream. It looks for a stream of type "EEG" which seems not to be available. Did you compile BCI2000 yourself? If so, you might update to the latest version of the SVN source tree, and recompile. This will give y...

Re: Need help connecting via LSL

Hi, our expert is on vacation, so I will try to help you with this. If you have a moving line, this means that data is coming in. If no signal is visible, two possibilities exist: 1) there is NaN data coming in, 2) the data has a large offset. To see what is the case, please right-click on the displ...

Re: including resting data with recording

Hi, BCI2000 will record data for all values of TargetCode, it is not possible to restrict recording to certain values of that. If you feel you are missing data, you may have got the SamplingRate wrong when considering the number of samples? Apart from that, I have difficulties understanding what you...
