[Eeglablist] cohangle distribution

Hi All,

I am working with the cohangle outputs from CROSSF. My question is about 
how exactly the angle that is output is computed. I'm assuming that it is 
computed as the angle of the vector sum of all of the individual trial 
phase differences. Is this true? I understand that the coherence is 
essentially the normalized length of the vector sum.

Also, I am interested in looking at the actual distribution of those 
individual trial phase differences. I can't find an option to output this. 
Has anyone else modified the code of crossf to access this information? If 
so, I'd be interested in seeing your modifications or just a description of 
where in the code to focus. Any help will be much appreciated.

Joe
