[FieldTrip] Source localization with 14-channels Emotiv Epoc EEG data

[Akanksha Tiwari]

Dear all,
I've recorded 14-channel EEG data with sampling rate 128 Hz recorded by
Emotiv Epoc. It was a resting state kind of study where I have the trials
length of 3–5 minutes.  I am planning to use the LORETA method in fieldtrip
for source localization, but in Emotiv Epoc most of the electrodes are in
the surrounding and there is no electrode close to the midline. Therefore
I've a few questions:
1. Is it worth applying source localization on 14 channels data with low
sampling rate (128 Hz)?
2. Does the method would make any bias as the electrodes are not uniformly
distributed over the scalp (Image attached)?

Thank you very much in advance.
