NAME

       m-anlz - Analyze (SPM) medical image format (MedCon)

DESCRIPTION

  This is a very simple format. The basic headers are written in one file with
  extension `.hdr', the image data in another file with extension `.img'.

  The basic defines for the format:

  ---------------------------------------------------------------------------

  typedef struct Header_Key_t{
          Int32  sizeof_hdr;               /* 348 or 148                 */
          char data_type[10];              /* "dsr"                      */
          char db_name[18];                /* filename without extension */
          Int32 extents;                   /* 16384                      */

  ---------------------------------------------------------------------------

  The structures are defined in the order as they should be found in the file.
  The Data_History header is not obliged. The SPM Analyze format, intended for
  the SPM software, differs a little from the normal Analyze format.

  What does the format support or not support:

  ===========================================================================
  Item            Supported                             Not Supported
  ===========================================================================
  Color Map     : grayscale                                   -
  File Endian   : little & big                                -
  Pixeltypes    : 1-bit, Uint8, Int16, Int32           Int8,Uint16,Uint32
                  float, double, (complex)               Int64,Uint64
  ===========================================================================
  Scaling factors  : quantify & calibrate factors/image  are NOT supported
  ---------------------------------------------------------------------------
  Dimensions/Image : different dimensions for each image are NOT supported
  ---------------------------------------------------------------------------
  Pixeltypes/Image : different pixeltypes for each image are NOT supported
  ---------------------------------------------------------------------------
  SPM remarks      : 1) imd.funused[0] = the offset
                     2) imd.funused[1] = one global scaling factor

NOTES

  A note about the image (patient) orientation in SPM:

       X-axis
            increases from leftside  (hand) to rightside (hand).

       Y-axis
            increases from posterior (back) to anterior  (front).

       Z-axis
            increases from inferior  (feet) to superior  (head).
