Comments
GeneStudio Pro (along with its free SeqVerter utility) was long popular in academic labs as an all-in-one Windows sequence converter, ClustalW alignment editor, and Sanger contig tool. Because development stopped around 2011 and the vendor site is offline, new users are generally better served by actively supported tools such as Chromas, UGENE, or CutePeaks.
