DEBrowser: interactive differential expression analysis and visualization tool for count data

Interactive Visualization and Analysis for Gene Expression Data

New technology such as DNA microarray can be used to produce the expression levels of thousands of genes simultaneously. The raw microarray data are images which can be transformed into gene expression matrices where usually the rows represent genes, the columns represent various samples, and the number in each cell characterizes the expression level of the particular gene in a particular sampl...

How to normalize metatranscriptomic count data for differential expression analysis

BACKGROUND Differential expression analysis on the basis of RNA-Seq count data has become a standard tool in transcriptomics. Several studies have shown that prior normalization of the data is crucial for a reliable detection of transcriptional differences. Until now it has not been clear whether and how the transcriptomic approach can be used for differential expression analysis in metatranscr...

An interactive visualization and navigation tool for medical volume data

Interactive direct volume rendering by hardware assisted 3D texture mapping has become a powerful visualization method in many different fields. However, to make this technique fully practicable convenient visualization options and data analysis tools have to be integrated. For example, direct rendering of semi-transparent volume objects with integrated display of lighted iso-surfaces is one im...

HDDVis: An Interactive Tool for High Dimensional Data Visualization

Current high dimensional data visualization tools are not effective in helping users gain insights of the data for many domains and tasks. This paper presents HDDVis, a very accessible High Dimensional Data Visualization tool that allows user to interactively explore the datasets from both low-dimensional projections and parallel coordinates. The dimensionality reduction methods used by HDDVis ...
