DanteR

DanteR is an entirely R-based program that provides a graphical front-end for common data analysis tasks in "omics", with an emphasis on proteomics. It is the successor to DAnTE, providing all of the previous features plus new functionality, including the imputation algorithm described in "A statistical framework for protein quantitation in bottom-up MS-based proteomics." by Karpievitch and Dabney (DOI 10.1093/bioinformatics/btp362).

IMPORTANT: Development of this program is frozen since it has been superseded by InfernoRDN, available on the InfernoRDN page or on GitHub.

This version is still made available because it implements the imputation algorithm described above (see "Model Based Filter/Impute/ANOVA" under the Statistics menu).

Area of Research: 
Description: 
    Supported file formats Excel, Excel 2007, SQLite DB, Access, CSV, tab-delimited text Supported locales US and European delimiters and decimals
    Data types Crosstabulated numeric data (peptide intensity, expression ratios, spectral counts, gene expressions) Metadata types Row metadata (proteins, pathways, biological functions)
    Column metadata/Factors (Experiment categories)
    Basic data operations Merge, sort, filter, apply arbitrary R commands Metadata operations Define row/column metadata, plot metadata linkages, create/apply aliases
    Preprocessing Normalization via eigenvalues, linear regression, LOESS, quantiles Imputation KNN, row means, model-based ANOVA, many others
    Peptide-to-protein rollup Via medians, means or quantiles Parametric statistical operations N-way ANOVA and robust ANOVA, two-factor protein-level ANOVA, Fisher test, model-based imputation/ANOVA
    Nonparametric statistics Shapiro-Wilks, Kruskal-Wallis Other statistical operations Interactive volcano plots, significance summaries
    Plotting Matrix/Scatterplot, 3D plots using RGL, histogram, QQ, boxplots, ellipses, Venn diagram Data exploration K-means and hierarchical clustering, pattern search, 2D and 3D PCA plot, dynamic metadata-linked row plotting
    Addons Users can include their own R-based addons to the program Addon dialogs A simple markup language allows dialogs to be created with no GUI experience
    Version: 

    v0.0.2, December 2010

    Downloads: 
    Software Instructions: 

    1. Download DanteR_Installer.zip , unzip, and run DanteR_Setup.exe

    • This installs DanteR, GTK+, and R
    • This will not affect any other copy of R you might have installed

    2. After the installer finishes, start DanteR using the link in the DanteR folder in the start menu, or via the desktop link

    • R Console will appear
    • After ~15 seconds, commands will appear in R Console and the DanteR window should appear

    3. See the PDF files for usage tips
