[Eeglablist] ITC Single Trial Phase Angles

I am looking for a way to get the phase estimates for single trials 
(for each frequency and time point) that go into the ITC computation. 
Basically, I want to plot the phase distribution on which the phase 
coherence ITC value is based. I'm using the ITC that is an output of 
timef. I know that there is a way to get individual trial phase 
estimates for crossf (using the flag/arg pair "savecoher',1 and 
adding an additional output variable to the call). Is there a way to 
do this for timef? I know that the "phasecoher" function returns 
single trial phases. However, I'd prefer to get this information out 
of the ITC output from timef because I will be looking at both ITC 
and ERSP and I would like the parameters (window-size, etc.) to be 
exactly the same and I have been using FFT which I don't see as an 
option in phasecoher. So, if someone knows how to do FFT in 
phasecoher, that could help too.

Thanks for any help that you can give.
