[Eeglablist] using EEG power data to plot topograhpic maps

[Min Sheng]

Hi All,

I am new to EEGLAB and would like to ask smb's assistance with importing of EEG data into EEGLAB and plot topographic maps.
My data is already preprocessed and saved in .mat files as 1 array for power of 31 channels(power, channel). I import this data to eeglab, but it always shows there is only one channel and 31 epochs,  I was trying to change the matrix to 31x1(channel, power), but it did not help.  I could not find the answer in help how to use the frequency power to plot topographic map.
Please help. Thanks a lot.

Min
