About the order of the extracted data by scout function

Hello,

I have one question about scout function.
Here, let me assume that I have 2 vertices(A & B), 2 trials and 1000 ms time series data.
When I apply scout function, I will get 4*1000 data.

I would like to know the exact order of these data.
Namely,

will the data be [A vertex1000(trial 1); B vertex1000(trial 1); A1000(trial 2); B1000(trial 2) ]

or [A vertex1000(trial 1); A vertex1000(trial 2); B vertex1000(trial1); B vertex1000(trial2)] ?

Many thanks for you kind support in advance!

Best wishes,

Hello,

I guess you meant “2 scouts (A & B)”?
In the output structure you get when using the process “Extract > Scout time series”, you will always find a field “Description” that tells you what each row represents.
I think in most cases, you should get [scoutA@trial1; scoutB@trial1; scoutA@trial2; scoutB@trial2], but double-check in your output structure.

Hello,

Many thanks for your correspondence.
I checked “Description”, which displayed showed as follows.

‘3 @Group_analysis/STI010__5/results_wMNE_MEG_GRAD_MEG_MAG_140923_1902_Subject01.mat’
‘4 @Group_analysis/STI010__5/results_wMNE_MEG_GRAD_MEG_MAG_140923_1902_Subject01.mat’

I guess that the initial number such as “3” and “4” indicates the scout number.
When my guess is correct, it means that I get [scoutA@trial1; scoutB@trial1; scoutA@trial2; scoutB@trial2].

Is my understanding correct?

This is correct, “3” and “4” indicate the scout names.
