clusteranalysis inter-trial phase-locking

I would like to use clusterrandanalysis to test significant differences of
inter-trial phase-locking values between conditions, within subjects.
I think clusterrandanalysis, with the 'indepsamplesZcoh' configuration needs
cross- and autospectra as input, to test between channel coherence differenes. 
I was wondering if there is a way to use this function to compute
inter-trial phase locking differences.

Thanks a lot for your help,


PS: I compute phase-locking with output='Fourier' and keeptrials='yes', in
freqanalysis. then:
frq.plv = squeeze(abs(mean(frq.fourierspctrm./abs(frq.fourierspctrm),1)));
I hope this is ok? 

would it be legitimate to change clusteranalysis to accept fouriersptrm as
input and introduce the phase-locking calculation step for every random
partition? then compute the z-statistics in clusterstatistics with those values?
