Bioinformatics is rapidly growing in importance in the annotation of genomic sequences, in the understanding of the interplay between genes and proteins, and so on. This proceedings contains an exchange of knowledge, ideas, and solutions to conceptual and practical issues of bioinformatics at the 4th Asia-Pacific Bioinformatics Conference.
