[FieldTrip] BrainProducts Easycap layout

Hi Hweeling,


If you create a text-file that has three columns: Label, Theta, and Phi
coordinate, you can use elec = ft_read_sens(filename) to read the layout
into a fieldtrip useable elec structure.

The first line of the text file has to be:


Site Theta Phi


You can also have a look at easycap-M1.txt and easycap-M10.txt in the
fieldtrip/template/electrode folder for an example of how the text-file
should look like.


The theta and phi coordinates will be converted to 3d coordinates assuming
a head-radius of 85mm (by default, you can specify this)

Subject: [FieldTrip] BrainProducts Easycap layout


Dear all,


I would like to know if anyone has the layout for 128 EEG channels for
BrainProduct easycap.


I have the information of the theta/phi coordinates for each of the
channels, but I'm not sure how to use these values to create the layout in


It'll be great if someone can help me on this!




Best regards,
