Signal quality okay?

Hi!

1. May I know if the data is good enough for analysis? If yes, what can you tell from the charts?
2. Should I worry about the markers?

The way to check signal quality is on the RAW EEG view with "All Data Points" enabled.
For good signal quality, you want the RAW EEG to only vary +/- by about 100uV.
BF - Bad Fit and J - Jaw Clench markers are a bad sign!

Yes. That looks great :-)
The sharp spikes are likely blinks.
