are true. Both conditions are present in all subjects, and the group
really is a group (ie groups '1' and '2' have different subjects - children vs
adults, and are not ways to sneak in extra conditions).</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=371491300-20102008><FONT face=Arial
color=#0000ff size=2>And all the electrodes are interpolated - I ended up using
v6.01 just to do the electrode interpolation, then switching back to
6.03b(oct2008) to pre-calc all the channel measures. Selecting the
individual setfiles and plotting ERP's also works fine, for both groups and
condition types, so I dont think the data is missing or wrongly arranged.
Any other hints?</FONT></SPAN></DIV>

[Eeglablist] comparing condition and group ERP's from a
STUDY<BR></FONT><BR></DIV>
<DIV></DIV>Dear Hamish,
<DIV><BR></DIV>
<DIV>some more information about groups and conditions. Optimally:</DIV>
<DIV><BR></DIV>
<DIV>- All conditions are supposed to be present in all subjects. If
not, the program should still work but might lead to the empty plots you
are seeing them right now.</DIV>
<DIV>- Groups are supposed to be for different subjects or different
sessions (different ICA decomposition for sure). Using groups within the same
subjects (to define a second condition) might work but not always. This is
pushing the limits of the program.</DIV>
<DIV>- You should interpolate missing electrodes. Once more, if you do
not do that, the program should work but the average will take into account
different subjects at each channel location.<BR>
<DIV><BR></DIV>
<DIV>We are working on these limitations. You will be able to select several
conditions and/or groups. </DIV>
<DIV><BR></DIV>
<DIV>Best,</DIV>
<DIV><BR></DIV>
<DIV>Arno</DIV>

<P><FONT face=Arial size=2>Now, when plotting the channel measures, I select
"plot conditions on the same panel", and get two plots as expected. The
first (group '1') has two lines, as expected. One is labelled '111' and
the other '122'. All OK. However underneath there is an empty plot,
labelled '2', but with no lines.</FONT></P>
<P><FONT face=Arial size=2>I thought this might be somehow a fault in my data
