BioWord is a powerful biological sequence editor operating in the most convenient of places: inside your usual word-processor (Microsoft Word 2007, 2010 and 2013). Easy to install and embedded into a Microsoft Office Ribbon, BioWord allows instant access to most sequence manipulation and editing needs, such as reverse-complementing, translating or FASTA formatting, and features a full suite of sequence search methods, pair-wise alignment and motif discovery. Check out the BioWord paper for further details.

Consensus logos

BioWord also allows generation of consensus logos to represent multiple sequence alignments (MSA). A cross between sequence logos and consensus sequences, consensus logos provide a textual representation of a MSA (or more frequently a sequence motif) that explicitly depicts conservation using the heights of consensus characters. This allows embedding in text a richer representation of the motif than the basic consensus sequence.
