Gmaj can be run in two different modes: as an applet over the world-wide web (for viewing data delivered from a server), or as a stand-alone application (for viewing data stored on your own computer). These modes are mostly similar but have a few minor differences, as noted below. View GMAs with this tool. Gmaj help you view and manipulate Generalized Multiple Alignments (GMAs) produced by sequence-symmetric alignment programs such as TBA (though it can also be used with MAF format alignments from other sources).
It can display interactive graphical and text representations of the alignments, diagrams showing the locations of exons and repeats, and other annotations -- all with the users choice of reference sequence.
