PRS Tool

Pathway Regulation Score Software

PRS software is a new pathway enrichment analysis tool with a MATLAB graphical user interface. The tool enables end users to analyze microarray gene expression data and run a pathway enrichment analysis using two different approaches, PRS and z-score. The tool provides end users with an option of assessing the statistical significance of the results along with the ability to navigate through the maps of enriched pathways where significant genes are marked with different colours.
