Dear Hui,<br>
<br>
Oh yes this is familiar to me. This is most probably because spectrum<br>
computation mistakenly calculate only the first trial of the data. I<br>
thought this was fixed in the updated version of EEGLAB. If you have a<br>
reason not to use the other versions, please check EEGLAB BUGZILLA 698.<br>
Below are the copy from there.<br>
<br>
spectopo.m line 650<br>
<br>
where, in my case, epoch_subset = [1 1 1 1 1 1...]. This analyzes only the<br>
first trial. This is unacceptably misleading, so let me report this as a<br>
blocker. I remember the same thing happened to me before and I fixed it for<br>
myself, but this time I totally forgot it and wondered what was wrong with<br>
my data. As a temporally solution, I added<br>
<br>
epoch_subset = find(epoch_subset == 1);<br>
<br>
in the line643 after 'else'.<br>
<br>
This does not happen when I use the ver. 6.01. I'm not sure though if this<br>
always happens.<br>
