[Eeglablist] FFT data with EEGlab, how to get them?

[Maria Jose' Esposito]

Hi everybody,
I've just started to use EEGlab 4.511 on a Matlab 7.0. I'm interested in 
extract from continuous EEG data (PSG) the  power spectrum of different 
bands frequencies (that I would like define by myself) from a specific 
channel, and then to have this data in a format (.txt is ok)  that allow me 
to export them into another software for statistical analysis.  I've 
already imported my raw EEG (from an EDF format) into EEGlab an I've done a 
visual artifacts rejection, but I have some problem in finding a function 
that allows to define spectral analysis features [e.g. frequency 
band-withs, spectral resolution (window on analysis, epoch lengh), how to 
add a cosine window, how to define the ovelapping rate].  I found in 
EEGlablist message archive that it is possible to do something similar 
by"phasecoher" function...is it in EEGlab or in Matlab?
Thank you very much.....I'm really looking forward to hearing from someone 
soon.
m.j.
