Peptrix

Peprix is a software application for label-free peptide profiling written in Java, using a MySQL database.

Peptrix is able to detect and identify significantly differentially expressed peptides in peptide profiles obtained from body fluids of patient and control groups. The presented modular software is capable of central storage of mass spectra and results in fast analysis.

The software architecture consists of 4 pillars

1) a Graphical User Interface written in Java,

2) a MySQL database, which contains all metadata, such as experiment numbers and sample codes,

3) a FTP (File Transport Protocol) server to store all raw mass spectrometry files and processed data,

4) the software package R, which is used for modular statistical calculations, such as the Wilcoxon-Mann-Whitney rank sum test.
