[Eeglablist] Questions about ICA Filtering...

[aparkr83 at siu.edu]

Hello all,

My name is Ashley Parker and I am a researcher in Dr. David 
Gilbert's Integrative Neurscience Laboratory at Southern 
Illinois University, Carbondale.  We plan to use ICA filtering 
for some EEG data we collected from 128 channels.  I was able to 
get 128 components for a practice file, but for others I 
recieved only 25 or even 13 components.  I was wondering what 
might be causing the low number of components on some files and 
then 128 on other files.  Would any one have any suggestions on 
how to fix this problem or tell me what I might be doing 
incorrectly?

Thanks,

Ashley Parker
