read_avw_complex

PURPOSE ^

[img, dims,scales,bpp,endian] = READ_AVW_COMPLEX(fname)

SYNOPSIS ^

function [img,dims,scales,bpp,endian] = read_avw_complex(fname)

DESCRIPTION ^

 [img, dims,scales,bpp,endian] = READ_AVW_COMPLEX(fname)

  Read in a complex analyse file into either a 3D or 4D
  array (depending on the header information)
  Uses avwcomplex to make temporary files for reading
  Ouput coordinates are in MEDx convention
  except that all dimensions start at 1 rather than 0
  Note: automatically detects char, short, long or double formats
  Extracts the 4 dimensions (dims), 
  4 scales (scales) and bytes per pixel (bpp) for voxels 
  contained in the Analyse header file (fname)
  Also returns endian = 'l' for little-endian or 'b' for big-endian

  See also: READ_AVW_HDR, READ_AVW_IMG, SAVE_AVW, SAVE_AVW_HDR,
            SAVE_AVW_IMG, SAVE_AVW_COMPLEX
