digeR: a graphical user interface R package for analyzing 2D-DIGE data.
2D Difference In-Gel Electrophoresis (2D-DIGE) or 2D gel technology is being used as a routine proteomics technique for biomarker discovery. Analyzing such high-dimensional data requires multivariate analysis techniques to be applied. In addition, protein post-translational modification (PTM) information from the 2D gel data is usually overlooked. We report on an R package, digeR, with an easy to use graphical user interface for analyzing 2D-DIGE (2D gel) data. It provides a tool for visually looking for potential PTM changes from different biological states and support biomarker discovery through multivariate analysis techniques.
