<DIV dir=ltr>Dear Xianghong,
<DIV><BR></DIV>
<DIV>> how to use the EKG and eye movement channels to get rid of the
artifacts from eye movements and EKG?<BR>
<DIV class=gmail_extra><BR></DIV>
<DIV class=gmail_extra>By running ICA including these channels. These channels
will 'tell' ICA about the artifacts to decompose.</DIV>

are very helpful.<BR>When we have channels for eye movements and EKG artifact,

you have to fit dipoles after ICA; b) dipole position inside the
brain.<BR><BR>> Plus, I saw eeglab could also analyse MEG data. Do we need
