  2. Features • Preprocessing • Log-transformation, replication handling, missing value imputation, filtering and normalization • Analysis Tools • Viewer • Unsupervised Clustering • Differential Gene Expression • Supervised Classification • Data Mining with Gene Ontology (GO) http://gepas.bioinfo.cnio.es/tools.html

  3. Pre-Analyses & Preprocessing • Pre-analyses • Preprocessing the data • Transform • Deal with replication and missing value • Filter patterns, standardize patterns • Filter genes

  4. After Preprocess
