Import scout time series from MATLAB

[chenfe]

Hi Brainstorm Team,

In Brainstorm, I want to do a CG analysis at the source level.

For each subject, I have source-localised all trials and extracted the scout time series for each trial.

However, I need to pre-process the time series to remove the stationary components.

I notice that there is a button called "Import from Matlab", when I right-click a scout time series in the Brainstorm GUI.

I am wondering if I can create a script to automatically import processed time series from MATLAB?

I'm looking forward to your reply. Thank you very much in advance for you reply.

Best,
Fan

Hi @chenfe

Yes this is possible, once you have your data in Mtlab, you can import it to Brainstorm,

Import script: fail to impose correct time window/freq recording

Hello, Importing recordings from Matlab matrices or text files is still handled with older interface functions. You can't set the import options from the process options. Three solutions to your problem: You load all your files with the interactive menu: right-click > Import MEG/EEG: This will ask you the missing information.

How are the Scout time series pre-processed?
If this is performed in for each file independently, and in Matlab, you could use the process Pre-process > Run Matlab command
