[Eeglablist] Channel Location File

Tue Dec 25 08:46:41 PST 2012

Hi, Andrew, 
    What a great Christmas present! Thank you much. 
   Two more question:
   1) since i use channel 10 and 21 as reference, do you still have the location for Cz or how can I generate it from other channels' location.
   2) whether the channel number in the file corresponding the sequence of the standard configuration which BV providing us like two sets with 32 channels each?
   Thanks again!

Hi Shou .. .here's your Christmas present

its in BESA format ... but EEGLAB will read it

it's 63 channels ... I used electrode #1 (Cz) as reference during the recording

cheers

Hi, Everybody,
    I am looking for a channel location file for Brain vision 64 channel active cap, I have one as attached, however, it can not be read by eeglab, and it seems miss some information about the 3D display.
   I have looked at the ftp for channel location files in eeglab, however, I can not find same one.
    Do you have any suggestions or where can I get one?
   Thanks
   Merry Christmas!
Shou

Dear Makoto,

Thank you very much for you vision, the problem was just there is a dot after the channel name in the Edit Channel window   i.e Fc5. when i remove the dot the Look Up Locs works perfectly

Best,
Khaled

Dear Khaled,

The channel labels must have 10-5 system nomenclature (which include 10-10 and 10-20 channel names). Double check it please. Could be case sensitive.

Dear Makoto,

First of all it's my fault for not being specific with my question.

When i open the Channel Location windows, it was supposed that the function will automatically look up channel locations for these known channel labels and when i pressed the Look Up Locs button, nothing happened
i'm working on this dataset if that helpful http://www.physionet.org/pn4/eegmmidb/

Best.

Dear Khaled,

If you have channel labels, then from GUI 'Edit' -> 'Channel locations'.

Dear Makoto,

I had the channel labels but when i'm asked for plotting Component Properties, Component Maps in 2-D or 3-D, message told me that " The functionality requires channel location information "
I feel like i need to read more, Thanks

Best,
Khaled

Dear Khaled,

If your imported dataset has 10/10 system channel labels, then EEGLAB can automatically takes care of it. If it does not, them give them channel labels first and let EEGLAB find positions.

Hi Khaled,

Depending on the system you used, you may find a file at http://sccn.ucsd.edu/wiki/Channel_Location_Files (make sure to check the files in ftp://sccn.ucsd.edu/pub/locfiles/). That website also includes a link to ftp://ftp.egi.com/pub/documentation/technotes/HydroCelGSN_10-20.pdf, which has tables for 10-20 that I assume you could use to create a location file (using the format of one of the other example files available in ftp://sccn.ucsd.edu/pub/locfiles/, and just putting in your own values for the electrode names and locations).

Best,
Steve

Hey,,

Where can i find the channel location file to download, if my data recorded according to 10/10 system and i have 64 channels.

Thanks in advance
