BioEdit is a mouse-driven, easy-to-use sequence alignment editor and sequence analysis program designed and written by a graduate student who knows how frustrating and time consuming it can be to rely upon word-processors and command-line programs for sequence manipulation. BioEdit is intended to supply a single program that can handle most simple sequence and alignment editing and manipulation functions that researchers are likely to do on a daily basis, as well as a few basic sequences analyses.
