[Eeglablist] neuroscan cap _ EEGLAB tools

[Zev Rosen]

Hi Maria,

Thank you for the quick reply! I followed the directions that your
colleagues instructed and created the spline.spl file from the .sfp file but
for some reason when running headplot.m the electrode locations are correct
in proportion to each other but not correct in proportion to the  entire
head ie PO8 is placed in a right parietal position instead of a right
occipital position.
Would you mind asking your colleagues who use quick cap to send us the
electrode location file that they use.  Epharisto! If anyone else on the
list has any ideas on how to help I would be very grateful.
