[Eeglablist] Fwd: SURVEY on recording 3D scalp electrode locations

[Scott Makeig]

Yahya Shirazi and I are in process of publishing a paper and further
tutorial material on recording scalp electrode positions in 3D using
photogrammetry (3D head scanning) - which is now the lowest-cost,
easiest-to-use method for performing this task that is crucial to
performing any type of brain source imaging from EEG recordings.

Please do not send your response back to the eeglablist! Please reply by
forwarding this email with your responses inserted to smakeig at ucsd.edu.

Note that responses to the last question below (Q6). are important to us!

        Thanks for your assistance,    Scott Makeig

SIX QUESTIONS ON ELECTRODE POSITION RECORDING

Q1. Do you or your lab record exact 3D positions of scalp electrode
placements in your experiments?

Q2. If yes, then what method do you use?

      Photogrammetry     Magnetic_based_system     Radio_based_system
 MR_head_image     Other

Q3.  If you do not use photogrammetry, what system name do you use?

Q3. If you do use 'photogrammetry,' what hardware scanner do you use?

Q4. If you do use 'photogrammetry,' what scanning software do you use?

Q5. If you do use 'photogrammetry,'  what electrode position locating
software do you use?

**Q6**  What exact peri-auricular (near-ear) fiducial locations do you
record?

Q6 Response (choose one):
         Green (right) - Preauricular (LPA|RPA)
         Blue (top) - Helix-Scalp junction (LHS|RHS}
         Grey (small) - Ear canal (LEC|REC}
         Red - Helix-Tragus Junction (RHT|LHT)
         No peri-auricular fiducials recorded.
         Other -   [please specify]
