Re: mem function

Qingjie, the mem mex file uses the burg method to estimate the spectrum of a given signal. You can find a description of the use on the BCI2000 wiki [1], you can also explore the MATLAB implementation [2], or alternatively look into the source code of the MEM implementation in BCI2000 [3]. If you li...

Re: Operator module configuration. 3 state bar right from each parameter

lsegura003, the slider with the three selectable states refers tot he user level, which can be beginner, intermediate and advances (see below). This is intended to lock down BCI2000 configuration abilities to only those relevant for a particular user. For example, if you want to avoid that the exper...

Re: Rythm isolation before ICA ?

Samhitha, if you bandpass filter your data into the relevant physiological bands (e.g., theta, alpha, beta, low gamma, high gamme, etc) it will be easier to make sense of your ICA components. Also remember that these physiological components have different amplitudes and SNR values, as the EEG signa...
