[Eeglablist] "How can I import data from the Quasar dry electrode headset ?

[Alistair Walsh]

Hi All,

I have some recordings from The Quasar system using their Qstates recording
software. The data has been converted to CSV and i can import it into
EEGLAB. I'm wondering how to specify channel locations for a 9 electrode
setup with the following locations -

f3, fz, f4
c3, cz, c4
p3, pz, CMF

The p4 location is used as a reference (common mode follower?) I think.
I can import a file but not sure about where everything is going. There are
a number of extra channels in the data file (time, trigger, offset). Do I
remove the time channel and other to just leave the 9 channels of electrode
data (with the sample rate giving the time information)?

I realise this is a very basic question but it is not explained in the
tutorial or manual. The links to external sites are also returning an
error.
