[FieldTrip] Estimate coherence between conditions?

[Maria Hakonen]

Dear FieldTrip experts,

I have just started to use Fieldtrip and would like to estimate coherence
between MEG responses measured in two different conditions from the same
cortical areas. The example in Appendix 1 is close to what I would like to
do:
http://www.fieldtriptoolbox.org/tutorial/coherence

However, in the example, coherence is calculated between the reference
signal (EMG) and all MEG channels. Could it be possible to calculate
coherence between each MEG channel in one condition and the same MEG
channels in the other condition, that is:
ch1 in cond1 vs. ch1 in cond2, ch2 in cond1 vs. ch2 in cond2, ...

As far as I understand, the example in Appendix 1 would do this:
ch1 in cond1 vs. all channels in cond2, ch2 in cond ch1 all channels in
cond2, ...

Best,
Maria
