NEW: We have updated the microarray expression compendia (CDF TAIR10 - Brainarray v14) (see FAQ). (01/12/11)
NEW: We have updated the experimental protein-protein interaction data (see FAQ). (25/08/10).
We have updated our co-expression tool. Correlation can be studied using multiple expression datasets simultaneously (see FAQ) (17/08/09).

The co-expression tool calculates the correlation between gene expression profiles using one or more precompiled expression datasets and as such identifies possible functional associations between genes.

The PPI tool interrogates available protein-protein interaction databases (both experimental and predicted interactions).

Integrate co-expression and protein-protein interactions: Start with the co-expression tool and continue on to the PPI tool or vice versa. You can also add localisation info in both tools. These options can be selected on the bottom of the page.

Browse experiments allows you to search the microarray experiments in the CORNET database using ontologies, download raw data and preprocessed data that can be used at a later time in CORNET or in other software.

Upload/Edit allows you to upload your personal microarray experiments into the CORNET system. After uploading, these experiments will be available through Browse experiments. (data is stored for 1 day - see FAQ for details)
