Example:
vshowpts -in pts.txt -system talairach -out pmap.v
vlview -in mr024_t1_pl.v -zmap pmap.v
The coordinates may be given as mm coordinates, Talairach or MNI coordinates.
Each line specifies one point and has the following format:
x y z id radius
Example:
10 20 35 1 2
10 23 24 1 2
18 33 17 2 3
This line produces two spheres of radius 2 and id '1', and one of radius 3 with id '2'.
The 'id' can be used to attribute different colors to the points.
Point with identical id's will have the same color.
Thus, if visualized using 'vlv','vlview','vlrender', the first two spheres will have the same color,
the third will have a different color depending on the color map.
The color map can be chosen interactively using 'vlview','vlv','vlrender'.
The dimension of the output image (its matrix size) can be specified using the parameters '-nslices', '-nrows', '-ncolumns'. If set to '0', a default value is used.
