Hello,

The SourceSignal window in BCI2000 is one of the most heavily used windows. Yet, it is often difficult to know which colored line corresponds to which electrode.

At present, on the far left of the SourceSignal window, you see the number for each electrode in the same color (cyan). I suggest changing this so that the color of each number is the same as the colored line it represents. For example, in one implementation of SourceSignal, every fifth electrode is yellow and all the others are white. I suggest making every fifth number on the left side yellow as well.

Hi Brendan,

to the right of each channel number, there is a tick mark which has the same color as the channel's signal.
The idea is to provide the user with the association between channels and colors, while at the same time keeping the numbers readable even for dark colors.

The colors are also user-configurable. When right-clicking a graph window, and choosing "Choose Channel Colors...", a Windows color chooser will appear. Its "User defined colors" will be used as channel colors in a cyclic manner -- the first black entry being the delimiter of the sequence.

Best,
Juergen
