Hi Maria,<br><br>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.
<br>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. <br><br>--Zev

<div><br></div>Kalimera Maria,<br><br>Hi I am a researcher at the University
of Pennsylvania and also use the neuroscan quickcap 64. I noticed that
you had posted on the EEGLAB bulletin that you had a channel location file
that can be used in the EEGLAB headplot function for doing 3d topographical
plots. We are having some trouble when using the headplot.m function
with the channel location .dat file exported from neuroscan and we would be
most thankful if you could send us your channel location file.
