<DIV><FONT face=Arial size=2>Dear Teresa,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can't really provide much info regarding your
first question, however, I might be able to help you with the second:
</FONT></DIV>
<DIV><FONT face=Arial size=2>Have you applied 'combineplanar' after the planar
transformation? This will combine the dH and dV pairs into one channel per pair,
e.g.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>cfg = [];</FONT></DIV>
<DIV><FONT face=Arial size=2>combplan = combineplanar(cfg, plan);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>were plan is the planar transformed data set.
combineplanar allows to choose the method for combination of the pairs. For
further details, you might want to have a look at the tutorial about event
related averaging:</FONT></DIV>

<DIV><BR></DIV><!-- Converted from text/plain format -->
<P><FONT size=2>Dear Fieldtripers,<BR><BR>I am using EEGLAB to compute ICA of
CTF 151 channels data.<BR><BR>I used to read the data in EEGLAB directly from
the CTF format,<BR>but some components are affected by the bad
channels.<BR><BR>Since removing the bad channels will reduce the number of
components<BR>and will give problems later at the planar transformation;<BR>I
tried using megrepair first and then importing the matlab array<BR>of
data.trial{1}. I use the channel locations of a previous<BR>dataset opened
from the CTF format.<BR><BR>- I still get some components reflecting the bad
channels,<BR>should I increase the cfg.neighbourdist? <BR>(I was using
the default of 4 cm).<BR><BR>- To import the data after the planar
transformation I need<BR>a channel location file for the dH and dV
pairs,<BR>can you help me with that?<BR><BR>Thanks in advance,<BR>Teresa
