# SVMDO ## Overview SVMDO is a R package providing Shiny-based web application for extracting disease-associated and normal/tumor tissue sample discriminating gene sets. ![](vignettes/algorithm_figure.png) Using FPKM and RPKM normalized RNA-Seq transcriptomics data, the package follows the steps displayed in **Figure-1**: 1. **Differential Expression Analysis**: Extracting differentially expressed genes from RNA-Seq datasets downloaded from either TCGA or GEO databases. 2. **Feature Selection**: Filtration of differentially expressed genes with Disease Ontology Enrichment Analysis. 3. **Gene Set Trimming and Classification**: Wilk's Lambda based discriminative gene set preparation for SVM classification. 4. **Prognostic Performance**: Single gene survival analysis of discriminative sets providing classification. ## Installation To install any package from Bioconductor, run the following command in your R console: ``` if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") ``` To install the SVMDO package using BiocManager, run the following command in your R console: ``` BiocManager::install("SVMDO") ``` The recent version can be downloaded from [Github repository]( ``` install.packages("devtools") devtools::install_github("robogeno/SVMDO") ``` ## Package tutorial A vignette file is available at [this link]( To see the html version, use vignette("SVMDO_guide.Rmd").
