Description of ExAtlas

ExAtlas is a tool for meta-analysis of gene expression data.
This is a mirror site at Keio University. If you have an account at the original site (lgsun.irp.nia.nih.gov/exatlas), then your account is already installed here, just log in. In contrast to other software, it compares multi-component data sets and generates results for all combinations (e.g., all gene expression profiles vs. all GO annotations). Main functions are: (1) standard meta-analysis (fixed and random effects, z-score, Fisher's method; analysis of (2) global correlations between gene expression data sets; (3) gene set enrichment; (4) gene set overlap; (5) gene association (Expected Proportion of False Positives, EPFP); (6) statistical analysis of gene expression (ANOVA, PCA, FDR). Results are presented graphically as heatmaps, bar-charts, or 3-D images (PCA). Gene expression data is extracted automatically from GEO/NCBI database. Several most popular public data sets (e.g., GNF, Gene Ontology, KEGG, GAD phenotypes) are pre-loaded and can be used for functional annotations.
