LIPSIA     Display outlines of activation areas of several zmaps
vzmapborder
In some applications, it might be interesting to compare several zmaps. The program 'vzmapborder' allows to merge several zmaps into one so that differences and similarities between zmaps can be visualized. An example is shown below.


Usage:
vzmapborder -in zmap1.v zmap2.v zmap3.v -out result.v -pos 3.0

The input images are several zmaps. The resulting image 'result.v' displays outlines of the individual zmaps thresholded at the given parameters '-pos' and '-neg'. Each outline of a zmap receives an individual code (code '1' for the first zmap, code '2' for the second zmap, etc.). The image 'result.v' can be visualized just like a zmap using standard visualization tools (e.g. 'vlview','vlrender'). By using an appropriate color table in 'vlview', the grey codes can be transformed into color codes.

If the parameter '-ref' is supplied, a 3D anatomical reference image is added to the output file.

Parameters of 'vzmapborder':
-help
Prints usage information.
-in

-out

-ref
3D anatomical reference file. Default: (none)
-pos
