[Eeglablist] inter trial coherence

[Makoto Miyakoshi]

Dear Jumana,

Sorry for belated response.

> Do you recommend bootstrapping & correcting for multiple comparisons at
the individual condition level?

No. Do it all at once in the STUDY.

I believe that ITC has a fundamental problem. Actually two problems at
least I know of. One was discussed in Martinez-Montes et al. (2008). One of
my colleagues investigated it, and I thought their criticism was legitimate.

The other problem is that if you have different number of trials across
conditions, comparisons across conditions does not seem valid due to
different signal to noise ratio.
