A reference guide for tree analysis and visualization

Georgios A Pavlopoulos, Theodoros G Soldatos, Adriano Barbosa-Silva, Reinhard Schneider
2010 BioData Mining  
In this study, we review tools that are currently available for the visualization of biological trees and analysis, mainly developed during the last decade.  ...  For example, the current phylogenetic tree visualization tools are not able to display easy to understand large scale trees with more than a few thousand nodes.  ...  The next section gives an overview of the most widely used tree-viewers for the analysis and visualization of data, primarily developed for phylogenetic analysis purposes, and covers mostly recent visualization  ...

SuiteMSA: visual tools for multiple sequence alignment comparison and molecular sequence simulation

Catherine L Anderson, Cory L Strope, Etsuko N Moriyama
2011 BMC Bioinformatics  
Multiple sequence alignment (MSA) plays a central role in nearly all bioinformatics and molecular evolutionary applications.  ...  Evaluating the quality of MSA reconstruction is often hindered by the lack of good reference MSAs. The use of sequence evolution simulation can provide such reference MSAs.  ...  This further assists comparative analysis of MSAs based on the "true" reference alignment where insertion and deletion events can be mapped individually onto both the guide tree and the true MSA.  ...

On the use of cartographic projections in visualizing phylo-genetic tree space

Kenneth Sundberg, Mark Clement, Quinn Snell
2010 Algorithms for Molecular Biology  
We present a definition of phylogenetic tree space and a visualization of this space that shows significant exploitable structure.  ...  Phylogenetic analysis is becoming an increasingly important tool for biological research. Applications include epidemiological studies, drug development, and evolutionary analysis.  ...  If it is not the visualization will not be able to be used in real time to guide a search. • The visualization should reveal exploitable structure.  ...

Mira Sarkis, Cyril Concolato, Jean-Claude Dufourd
2015 Proceedings of the 2015 ACM Symposium on Document Engineering - DocEng '15  
In this paper we describe a multiscreen-oriented approach for segmenting web pages. The segmentation is an automatic and hybrid visual and structural method.  ...  Results are compared with one seg-mentation method from the literature and with a ground truth manually created.  ...  For instance the hybrid VIPS [1] , based on the joint DOM and visual analysis, utilizes both structural information in the DOM tree and visual cues to semantically segment a page.  ...

Methods for simultaneously identifying coherent local clusters with smooth global patterns in gene expression profiles

Yin-Jing Tien, Yun-Shien Lee, Han-Ming Wu, Chun-Houh Chen
2008 BMC Bioinformatics  
The hierarchical clustering tree (HCT) with a dendrogram [1] and the singular value decomposition (SVD) with a dimension-reduced representative map [2] are popular methods for two-way sorting the gene-by-array  ...  The resulting algorithm automatically integrates the desirable properties of each method so that users have access to a clustering and visualization environment for gene expression profiles that preserves  ...  Acknowledgements The authors are grateful to Donald Ylvisaker, Konan Peck, Chiun-How Kao, and ShengLi Tzeng for valuable suggestions and assistance.  ...

Visualizing the Intellectual Structure with Paper-Reference Matrices

Jian Zhang, Chaomei Chen, Jiexun Li
2009 IEEE Transactions on Visualization and Computer Graphics  
Visualizing the intellectual structure of scientific domains using co-cited units such as references or authors has become a routine for domain analysis.  ...  Instead of using a reference-reference matrix, we directly use the original paper-reference matrix as the information source, and transform the paper-reference matrix into an FP-tree and visualize it in  ...  Thomson Reuters provides the bibliographic data for the analysis. We also thank Michael S. Vogeley, Danny Pan and John Parejko for their constructive suggestions on the SDSS case study.  ...

Overview of Data Visualization [chapter]

Qi Li
2020 Embodying Data  
Humans often use trees as a symbol to represent classification of the natural world (Lima, 2011) . In visualization, tree can also refer to "Tree-Map" visualization (Johnson & Shneiderman, 1999) .  ...  For example, The Diagram Displays a Relationship and Information Flow for a Business System Analysis by Gerald Lohse emphasizes that the addition of background shading could enhance the understandability  ...
