CATdb contains data on  112 projects  (3538 hybridized samples)  in public access out of a total of 192 projects (~7528 hybridized samples). The data are released one year after their production.

You can access data by experiment or by probe through:

• A table of all projects.

• Keywords search on experiment description.

• Gene or probe accession query.

More information to explore CATdb

CATdb collects together all the information on transcriptome experiments done at   URGV  with   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  , 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.
