vReCalcSignMap.m
The function calls vFieldSignMap to re-calculate the visual field sign map in mrFindBorders
based on the pre-processed data, e.g, after changing the coherence threshold or the phase off-
sets.
6.16 UI
Displaying images in the right way, e.g. with a suitable color map, is important. This is just
one example. Many more problems had to be solved. Another example is the problem of how
to overlay ROIs onto the functional data. Although a big effort has been made to create func-
tions that allow an easy handling and viewing of data, the functions are explained only very
briefly here. Please refer to the source code for more insights.
vGetCurrentCuCv.m
This function returns the displacement fields for the control points (cu and cv) according to
the current data set (currently selected resolution).
vGetCurrentUV.m
This function returns the displacement fields for all pixels (u and v) according to the current
data set (currently selected resolution). If u and v have not already been calculated, they are
calculated based on the displacement fields for the control points (cu and cv).
vGetPoints.m
vGetPoints asks the user to specify points in fovea or boundaries. It is possible to pass points
that are already specified to the function. The user can then decide whether to keep the old
points. If points are to be specified in one of the boundaries, the user has to draw a line across
the boundary. An image profile is displayed, in which the user has to specify the location of
