> Hi all,
>
> I am having issues with importing the channel locations of a BioSemi 128 electode system. This system follows non-standard naming (ABC), and thus the loc/sfp/elp files in eeglab do not work for my system, even if I rename the electrodes.
>
> I imported my own XYZ coordinates in a .sfp file, but eeglab GUI does not put them in their correct boxes (will put the Y value in the X box, and put a -X value in the Y box). The best I have done is in the photo below - but there are several electrodes outside the scalp when they should be in.

> Does anyone have a similar experience and/or solution?

> Thank you!!
