[Eeglablist] could someone send me the EGI.129.elp channel location file?

[Joseph Dien]

I'm honestly not sure what the files in the EEGlab supporting files 
directory correspond to.  The simplest thing might be to just download 
my EP Toolkit at: https://urldefense.com/v3/__https://sourceforge.net/projects/erppcatoolkit/__;!!Mih3wA!GeSdvnzEmDeADjs2PE-iQOxc6qxWaNAAk3b2J7nK28VrpuyHf9hLUT7ZI008XPtAIj_LTmdcuQ0pDReIBF0$ 


It has a folder named "electrodes" that has the .ced files for the old 
GSN nets, the original age non-specific Hydrocel coordinates (in a 
subfolder named old EGI Hydrocel), and the newer Hydrocel ones.  The 
newer ones for adults are named along the lines of 
AdultAverageNet128_v1.ced.  The ones for children are named along the 
lines of 2_9AverageNet64_v1.ced, meaning for ages 2-9.  The original 
coordinate files were all provided by EGI, so they're official.  You'd 
have to ask them directly for any more information.


They should be directly usable in EEGlab, although I added some EP 
Toolkit specific additional columns that eeglab will just ignore.


You can just ignore the rest of the download, although I'd be happy to 
answer any questions about it.  I'm about to release a newer version 
with an improved tutorial.


Cheers!


Joe
