Within-subject coherence statististics for virtual sources

Dear FIELDTRIP members,
I have used BESA to perform source coherence
calculations for a multiple-subject/multiple-condition experiment. I have 14 subjects, and 2 conditions for which Id like to compare coherence values. I have calculated coherence values in the Time-Frequency domain for each person.
Given that BESA cannot calculate statistics in a multiple-subject study, their support personnel directed me towards FieldTrip.
I would like to use your existing script clusterrandanalysis on TFRs of power that were computed with BESA, but I cannot relate this to my data as the coherence values have been calculated for ROI sources, (8 per hemisphere - 16 sources total), and not for electrodes (I had 128).
Do you have any advice regarding how I may adopt the script to for source coherence as opposed to electrode coherence? How do I import the source locations?
Many thanks is advance for your help,
