Sensor positioning

Positioning sensors correctly relative to the render model allows you to adjust the mapping of the signal on the surface. There are four types of adjustments: an "y-offset" which acts in along the anterior-posterior dimension, a "z-offset" which operates along the "inferior-superior" dimension, an "x-rotation" along the left-right dimension and a "theta-scaling" which is similar to the z-offset but keeps theta angle proportions constant.  These transformation are configured on the "positioning" page in the VIEWAVERAGE section of the configure-study dialog. Similar controls are available in the

The effects of the transformations are illustrated below:

Y-Offset and Z-Offset transformations are spherical projections on a translated model as shown in the following graph, sensor distances are not proportionally transformed.
