** How to create Analyze(LAS) file from DICOM file

- There is converter function.
      convert_dicom_nifti

  In the appearing dialog, input one of the dicom files.
  Analyze(LAS) file will be created. (LAS*.(hdr/img))

** Face extraction result is bad.

- Try to apply a bias correction to Analyze(LAS) file.
   bias_correction_by_spm(AnalyzeLAS);

   This function do a bias correction with the help of SPM .
   Add SPM(2/5/8) path into your MATLAB path and then call the VBMEG function.

   mAnalyzeLAS will be created.(prefix 'm' is added.)

   Note: SPM(5/8) put file as a NIfTI format.
         bias_correction_by_spm changes data format 
         to Analyze format after finishing bias correction.
         So please use this function when you use SPM5/8.
