Integrative analysis of complex cancer genomics and clinical profiles using the cBioPortal
(American Association for the Advancement of Science (A A A S), 2013)The cBioPortal for Cancer Genomics (http://cbioportal.org) provides a Web resource for exploring, visualizing, and analyzing multidimensional cancer genomics data. The portal reduces molecular profiling data from cancer ... -
Investigation of multi-objective optimization criteria for RNA design
(Institute of Electrical and Electronics Engineers, 2017)RNA design is the inverse of RNA folding and it appears to be NP-hard. In RNA design, a secondary structure is given and the goal is to find a nucleotide sequence that will fold into this structure. To find such sequence(s) ... -
k-Shell decomposition reveals structural properties of the gene coexpression network for neurodevelopment
(Scientific and Technical Research Council of Turkey, 2017)Neurodevelopment is a dynamic and complex process, which involves interactions of thousands of genes. Understanding the mechanisms of brain development is important for uncovering the genetic architectures of neurodevelopmental ... -
A layout algorithm for signaling pathways
(Elsevier Inc., 2006-01-20)Visualization is crucial to the effective analysis of biological pathways. A poorly laid out pathway confuses the user, while a well laid out one improves the user's comprehension of the underlying biological phenomenon. ... -
A layout algorithm for undirected compound graphs
(Elsevier Inc., 2009-03)We present an algorithm for the layout of undirected compound graphs, relaxing restrictions of previously known algorithms in regards to topology and geometry. The algorithm is based on the traditional force-directed layout ... -
