[Eeglablist] channel location file

Dear all,

are there any channel location files for the Neuroscan QuickCap40 (40 
channels) available? On the Neuroscan ftp I only found "dave.zip" which 
contains 32 and 64 channels + I get an error when I read those in, anyway.

And a second question:
I'm playing around with ICA to reject ocular artifacts from continuous 
data. Up to now I could find only few papers about the validity of 
ICA-corrected data. I'm asking myself that question because very often I 
get components representing the ocular artifacts, but they also seem to 
contain eeg-information, especially when I use the fastica algorithm. 
This results in quiet different looking signals in sections where no 
artifacts occur - mainly in frontal channels of course.

Any help is highly appreciated.

Thanks!

Michael
