[FieldTrip] Template for Electrode Positions

[Herring, J.D. (Jim)]

Dear Keyvan,

 

As is stated on http://fieldtrip.fcdonders.nl/template/electrode,
Fieldtrip also has electrode positions for the standard 10-20 system,
namely: standard_1020.elc.

 

To read in the sensor positions you would have to do something like: 

Filename = 'c:\fieldtrip\template\electrode\standard_1020.elc';

sens = ft_read_sens(filename);

 

 

Best,

 

Jim

Subject: [FieldTrip] Template for Electrode Positions

 

Dear all,

I want to do EEG source reconstruction. The EEG cap we used is the
standard 10-20 system with 64 channels, but the MRI and electrode
positions of  subjects are not available. I'm thinking of using Fieldtrip
templates.

 

For head model I used:

 

load standard_bem.mat

cfg.vol=vol;

 

But for Electrode positions I checked all options at this link:

http://fieldtrip.fcdonders.nl/template/electrode

 

the only option with 64 channel is GSN-HydroCel-64_1.0.sfp. It includes
labels in this format:

E1 E2 E3...

 

So, How can I use it for my work?

 

 

Best, 

Keyvan
