[Eeglablist] EGI channel locationsq

[Joseph Dien]

Cz is indeed in the EGI .sfp file at the website you listed.  I just downloaded it and looked.  It’s the last channel.  It should be in your data too.  It’s used as reference during data collection though.  In what sense are the locations different?

I wanted to double check that these were the correct locations so I uploaded 128 BESA cartesian (EGI not MatLab) channel locations from here <https://www.egi.com/knowledge-center/item/71-sensor-position-files-for-visualizing-data-in-third-party-software?highlight=WyJzZW5zb3IiLCJzZW5zb3JzIiwic2Vuc29yJ3MiLCJzZW5zb3JlcyJd>. The locations are different, and neither seems to include CZ.  I was wondering if anyone could tell me which channel locations to use and if it is normal to not have CZ as a point on the plots. Thanks so much for your time.
