Hi,

SB suggested to try dPTE on my models, but as I'm interested in subcortical structures I generally used mixed or volume source models. I have been experimenting with first extracting time courses from scouts, but am uncertain as to whether there is yet an approved method concerning the parameters for extraction for the purposes of PTE analysis, for example would it make sense to use the 'norm of x,y,z' option? The norm is always positive, so does that mean I should be looking for my frequency of interest at 2x the original frequency? And that after mean or PCA for time series extraction?

Or alternatively, would it make sense to run the PTE on each of the three directions and then average them somehow afterwards?

And would the source wMNE depth weighting parameter affect the effectiveness of connectivity analyses for connectivity analyses such as these?

Any advice would be welcome !
