Table 1 Comparison of functionalities among AMDA and other software that perform a full microarray data-analysis The functionalities provided by AMDA are reported in the first column, with comment or list of methods or DBs where necessary. The remaining columns show whether other software that perform a full microarray data-analysis provided the same features. A plus indicate that the software provides it and, when applicable, the same set of methods. A minus indicates that the functionality is not provided. Text is used to report in case the provided features are different. Finally, italic text is used to identify functionalities for which the provided methods are a sub-set of those available in AMDA.
