(This is for a stand-alone four-component rotation. It can be skipped if the full Anisotropy Wizard will be run as it is also part of that processworkflow.)
i. In the Geophysics Toolbar, expand the options for Anisotropy processing (click the inverted triangle on the lower right corner of the button)
