query on confidence limit, DICS

[Muthuraman Muthuraman]

Hello

As i am able to sucessfully use the coherence analysis using freq_mtmfft and
frq_mtmwelch to calculate the coherence
i would like to know is there a way to calculate the confidence limit for
the coherence calculated from the freqanalysis, is there a standard code

Next, i would like to follow with the source analysis 'DICS' is there a
tutorial available

thanking you

with regards
Muthuraman
