Preface: Computational systems-biology and bioinformatics

In the era of big data challenges, as the availability of biological information becomes ever larger and more complex, more computational tools are needed to sort through the data. In particular, the fields of systems biology and bioinformatics have experienced a very rapid growth in the amount of raw genomic and post-genomic data being generated, thus enabling readily integration of different levels of data to provide better insights at the systems-level. The Fourth International Conference on Computational Systems-Biology and Bioinformatics (CSBio 2013) was organized to provide a forum for like-minded researchers and industrial counterparts to share and exchange ideas and stimulate research growth. CSBio 2013 was organized by Yonsei University and it was held on November 7-9, 2013 at Yonsei Engineering Research Park in Seoul, Republic of Korea.
