This book constitutes the refereed proceedings of the 12th International Workshop on Algorithms in Bioinformatics, WABI 2012, held in Ljubljana, Slovenia, in September 2012. WABI 2012 is one of six workshops which, along with the European Symposium on Algorithms (ESA), constitute the ALGO annual meeting and focuses on algorithmic advances in bioinformatics, computational biology, and systems biology with a particular emphasis on discrete algorithms and machine-learning methods that address important problems in molecular biology. The 35 full papers presented were carefully reviewed and selected from 92 submissions. The papers include algorithms for a variety of biological problems including phylogeny, DNA and RNA sequencing and analysis, protein structure, and others.

This book constitutes the thoroughly refereed post-proceedings of two joint RECOMB 2005 satellite events - the First Annual Workshop on Systems Biology, RSB 2005, and the Second Annual Workshop on Regulatory Genomics, RRG 2005, held in San Diego, CA, USA in December 2005.

The 21 revised full papers presented were carefully reviewed and selected for inclusion in the book. The papers address a broad variety of topics in systems biology and regulatory genomics including inference of gene regulatory and protein signaling networks, model prediction of drug mechanism, pathway mapping and evolution in protein interaction networks, multi-scale methods which bridge abstract and detailed models, systematic design of genome-scale experiments, modeling and recognition of regulatory elements, identification and modeling of cis-regulatory regions, modeling the structure and function of the regulatory region, and comparative genomics of regulation.
