Widely used in evolution research, biogeography, and other biomedical fields, it offers many features not found in competing programs, including the ability to compare contigs with ClustalW and muscle, trace sharpening, roundtrip editing, and base calling with PHRED, as well as standard features like assembly, trace and contig editing, end clipping, and mutation detection.
