This is a functional index of methods available on a statistic_image
object. statistic_image is a subclass of image_vector for storing
and manipulating statistical images (t-maps, p-maps, thresholded
results). Multiple images can be stored in a single object, thresholding
is reversible (via the threshold method) without changing the
underlying values, and standard visualizations (orthviews, surface,
montage) honor the .sig field so only suprathreshold voxels are
shown.
This class also inherits all image_vector methods listed in
image_vector_methods.md. Only methods owned
by statistic_image (defined in @statistic_image/) are listed below;
where a method also exists in @image_vector/, the statistic_image
override wins. Type methods(my_obj) in MATLAB for the live list on
any instance.
statistic_image inherits all image_vector properties (dat,
volInfo, removed_voxels, removed_images, image_names, fullpath,
files_exist, history, dat_descrip, source_notes) and adds the
following:
