vb_load_analyze_to_right

 Load Analyze/Nifti file to RAS image
  [B, Vdim, Vsize] = vb_load_analyze_to_right(fname)
 --- Input
 fname - Analyze/Nifti filename 
         Default Analyze file is left-handed  LAS image
         Default Nifti   file is Right-handed RAS image
 --- Output
 B     : 3D image data  [Xdim, Ydim, Zdim ]
 Vdim  : image size  [Xdim  Ydim  Zdim ] (voxels)
 Vsize : voxel size  [x y z ] (mm)
 Trans : transform matrix from voxcel to Right-hand mm coordinate
   [x  y  z  1] = [i  j  k  1] * Trans
