4.8 Menus
The various menus are explained next. In the menus, inactive command names are displayed
in a light-gray color. Active command names are displayed in black.
4.8.1 File Menu
·
The File menu (Figure 27) allows the user to load and save data. This includes phase
and coherence images for rotating wedge and expanding/contracting ring stimuli.
These images can be loaded in different ways, i.e., by using a mrSESSION file, or by
loading exemplary flat data files (“Huk” and “Alyssa” flat data sets). Instead of load-
ing measured data, the algorithm can also create data, which is then used as a replace-
ment for measured data. The data is created by using the same function that creates an
atlas. The images are then rotated and manually deformed. In addition, noise is added.
This functionality is useful to test the algorithm.
·
It is possible to save and load the set of variables that is used by mrFindBorders at any
time. This includes all images, options, and results. This feature is very useful since
the results produced by mrFindBorders can be reproduced easily later if the user saves
the data including all options.
·
Furthermore, the displacement fields for the control points (initial data set) can be
saved and loaded separately. Control points are a subset of all pixels in the image on a
regular grid. The displacement values for the control points define the deformation of
the atlas image. More information on this is given later. If the user would like to save
displacement fields from other data sets, it is possible to copy the data from the cur-
rently selected data set to the initial data set (Edit menu). The initial data set’s dis-
placement fields can then be saved.
