Introduction & Features

The mpc Statistical DIGE Analyzer is a Java-application for the statistical analysis of data from 2-Dimensional Difference Gel Electrophoresis (DIGE).

- Simultaneous differential analyses of thousands of protein spots: t-tests, fold change (plus respective confidence intervals), p-value adjustements (Bonferroni, Benjamini-Hochberg).
- Power analysis for sample size calculations.
- Principal component analysis for comparing between gel variation.
- Analysis of 'Minimal' and 'Saturation' designed studies.
- Calibration of raw spot intensities (Quantile Normalization).
