 brede_ta3_volslice    - Construct 3D Talairach volume slices

       function h = brede_ta3_volslice(S, ...
            'PropertyName', 'PropertyValue')

       Input:    S          Volume structure
       
       Property: Colormap   [ {gray} | hot | ... ] Colormap for the
                            slice. Can either be a string or a matrix
                            as, eg, return from the 'hot' function.
                 Orthotype  [ {transversal} | coronal | sagittal ]
                 Position   [ {0} ] Where to position the slice, eg,
                            if 'orthotype' is 'transversal' a
                            'position' of 0.065 will position the
                            transversal 6.5 centimeter above the AC-PC
                            line
                 Range      Range for the colormap
                 Threshold  {NaN} Threshold for transparency. Only
                            values above the threshold are opaque. 
                
       Output:   h          Graphic handle

       This function will construct an orthogonal slice of the
       volume. 

       Right clicking on the geometry (the slice) will produce a
       menu. 

       Examples:
         % If SPM99 is in the path: load single subject MNI template
         fn = [fileparts(which('spm')) '/canonical/single_subj_T1']  
         S = brede_read_analyze(fn) 
         % Render a sagittal slice a bit to the right of the
         % ACPC-plane excluding voxel (pixels) under the value 50000
         brede_ta3_volslice(S, 'position', 0.03, 'orthotype', ...
               'sagittal', 'threshold', 50000)

         fn = [ fileparts(which('spm')) '/templates/PET' ];    
         PET = brede_read_analyze(fn);
         brede_ta3_frame
         brede_ta3_volslice(PET, 'orthotype', 'sagittal', ...
            'Position', -0.01, ...
         'Colormap', jet, ...
            'Threshold', 0.002, ...
            'Range', [0.002 max(PET.volume(:)) ]);
