[FieldTrip] Cluster analysis on correlation statistics

Dear all 

I would like to use the cluster analysis functions in Fieldtrip on
correlation statistics. I note there has been some discussion about this
on this list in the past but I haven't come across the necessary
ft_statfun_corr function to allow this analysis. It would be great if
somebody has this code and could share it with me; otherwise, I will
embark on writing it myself and sharing my results with everyone for
feedback. Being new to Fieldtrip I would greatly appreciate any
collaborative help with this. May I check my understanding on something
before getting started: To allow for multiple comparisons correction
using monte carlo for example, as part of a cluster analysis, I presume
the output of the function must be t values rather than correlation
coefficients? Any other hints as to how to write this are most welcome. 

Kind regards
