Lagged coherence

[Raymundo.Cassani]

The issue is that the data to export is 4D [nSensors, nSenstors, nWindows, nFrequency]. You need to collapse either the time of the frequency dimension. Check this post:

About connectivity parameters for Wpli and -lagged Coh

@tourette95, the exporting (to Excel) was designed to export one Excel sheet with one NxN connectivity matrix. In your case, these metrics are time-resolved (windowed) and frequency-resolved (spectral) metrics, thus, there is an NxN matrix for each window and for each frequency point. As @Marc.Lalancette mentioned, this feature is not supported in Brainstorm yet. As such, for the moment, if you want to export the a time-resolved spectral connectivity metric, it is necessary first to extract one …
