Scout time series to matlab

how can I export scout time series from brainstrom to Matlab workspace
I need to scout time series to calculate connectivity between ROIs in matlab?
please guide me for this subject via Brainstorm GUI

Use the process "Extract > Extract scouts time series" or "Extract > Extract values" to save the scouts signals to proper files in the database.
Then load these files with the Matlab load() function or using the menu "Export to Matlab".

Reading the entire Scripting tutorial page would probably help you for a general understanding on how to interact with files from the Brainstorm database from Matlab scripts.
