EEG Coordinates

  • Open MATLAB, run brainstorm
  • Use default anatomy ICBM 152
  • File > new subject > use default anatomy
  • Import EEG
    • Can select all data or just one trigger type
  • Right click on subject > Review raw file > Imports raw data
  • Right click on channels > MRI registration > Refine using head points
  • Right click on channels > MRI registration > Edit
  • Project labels to surface
  • Refine registration to head points
  • Ok
  • Yes
  • Right click on channels > Edit channel file
    • Allows you to se the channel loc coordinates
  • Right click on channels > File > Export to matlab
  • Go to convertCoor.m
    • Change the 'Type' in the EEG struct from 'EEG' to 'ECOG'
  • Go back to Brainstorm
  • Right click on channels > File > Import from matlab > select struct with 'ECOG' type
  • Right click on channels > MRI registration ? Edit … (cortex)
  • Project electrodes on surface
  • Ok
  • Yes
  • Right click on channels > File > Export to matlab
  • Go to anatomy page in brainstorm > Right click on MRI: ICBM152 > File > Export to Matlab
  • In matlab run loop to get x y z loc data array
  • Run cs_convert to transpose those coordinates to MNI (*1000 to put into correct units)
  • Save out as table
  • Open terminal
  • ssh -Y r
  • cd to directory with bash script
  • vim EEGcoordinatesAtlas.bash if you need to edit the script
  • Click 'a' to insert
  • esc to exit insert mode
  • Type ':wq' to write and quit
  • bash EEGcoordinatesAtlas.bash to run
