CATdb collects together all the information on transcriptome experiments done at  URGV URGV  with  CATMA CATMA  micro arrays  


All data in CATdb come from the URGV micro array platforms. Common procedures are used including any steps from the experiment design to the statistical analyses. Directed through a WEB interface, biologists enter the standard description of each experimental step (extraction, labelling, hybridization and scanning). Then, normalization and statistical analyses are done following a set of selected methods depending on the experimental design and array types (More on statistical analyses for CATMA).


CATdb contains many links to  FLAGdb++, a database for the functional analysis of plant genomes that graphically displays a wide range of Arabidopsis genome annotations including complete information concerning micro array probes.
