Dear fieldtrip users,<br>
<br>
There are different ways of estimating the covariance for LCMV
calculation.<br>
If I am correct: <br>
<br>
1. As suggested in one of the tutorial one can apply the calculation
of the covariance directly on the average data (for the different
periods of interest that are at least a base line and the period of
interest).<br>
<br>
2. Estimate the covariance from the average of the covariance rather
than the covariance of the average using cfg.keeptrials = "yes"<br>
<br>
3. Estimate the covariance from the whole trials concatenated
together. <br>
Is there an easy way to do that in fieldtrip (beside create a new
data set of one trial constituted of all the trials)?<br>
<br>
Thanks<br>
<br>
Jean-Michel<br>
