The Dialog is used to align a number of selected proteins (see ent). The user selects an alignment method charite.christo.strap.extensions.MultipleAlignerClustalW. By pressing the button ChButton#BUTTON_GO the alignment computation is started. It takes some seconds to minutes, before the computation the result is shown in a preview panel. To accept the alignment in the preview and to infer the alignment into the working alignment panel DialogAlignResult#BUT_LAB_Apply needs to be pressed to. 3D-alignment programs consider the 3D-structure. If not all proteins have 3D-coordinates, then the Strap uses a combination of 3D- and sequence alignment.
