  • Description
  • Conversion tool for Biosemi files to EEG format.

  • Usage
  • biosemi2eeg mybiosemifile.bdf myeegfile [myparfile]

    with :

    • mybiosemifile.bdf : Biosemi file to convert (with extension).
    • myeegfile : output EEG file (no extension).
    • option :
      myparfile : text file containing conversion parameters (electrode names and numbers). If this file is omitted, names are read from the Biosemi file and the first entry corresponding in elec.dat is choosen.


  • Fields of parameter file and example
  • electrodes
    P1.21
    P2.22
    H1.1091
    H2.1092
    A1.225

    Status.-1
    Output channel name list :

    Names and numbers corresponding to elec.dat definition for converted channels, or name and -1 if the channel is not defined in elec.dat.

    The order should be the same as in the input Biosemi file.
