Microarray Logic Analyzer Software

ABSTRACT

Clustering and classification of gene expressions are common tasks in microarray analysis. We designed and implemented a software - called Microarray Logic Analyzer (MALA) - able to classify the microarray experiments and to cluster the gene expression profiles. MALA uses a supervised machine learning paradigm and is composed on the following computational steps: - Discretization; - Gene clustering; - Feature selection; - Formulas computation; - Classification. After the introduction of the microarray technology this technical report describes MALA methods, software modules and its deployment with different user interfaces. The software is tested successfully on two real public available gene expression profiles and on a private real microarray Alzheimer data set. MALA is able to identify logic classification rules that distinguish the different classes of the microarray experiments and to cluster similar behaving genes. In conclusion, MALA is a powerful and reliable software for microarray gene expression analysis.
