Exporting time series to matlab

Discussions

Hi everyone,

I'm relatively new to Brainstorm and using it for source localization for my undergrad research. I have been trying to figure out a way to export the scout time series to Matlab but haven't found any luck. I specifically want to export the PAS-B12 Lobes time series to a .mat file.

Hi @a13,

To export the Scout time series as variables you can:

  1. Use the process process_extract_scout: Process "Extract > Scouts time series".
    Set Atlas, Scouts, Scout function and other options according your needs
  2. Run the process, a matrix file (iconMatrix) with the desired time series will be created.
  3. Right-click on the matrix file and select "File > Export to Matlab"
  4. The Scout time series are in the Value field of the exported structure

Best,
Raymundo

This error happens because the input files in the Process1 were none or wrong type. In fact the process process_extract_scout should have been grayed out.

The Extract > Scout time series process needs source files as inputs: iconResultLink or iconResult
