eVOKE is a browser-based JAVA client for the eVOC platform, a combination of orthogonal ontologies used to manually curate over 8,000 cDNA expression libraries, and the resulting mappings between annotations, libraries and gene identifiers such as UniGene Clusters or Reference Sequences.

eVOC Query Interface

The eVOKE query interface is currently in beta testing mode. If you would like to give the system a try please take a look at the installation instructions, then proceed to the eVOKE test page.

If you encounter any problems or have questions about the process please do not hesitate to contact Oliver Hofmann via electronic mail at ohofmann_at_hsph.harvard.edu.


WCD is a DNA sequence clustering tool, developed by Scott Hazelhurst and his team at the University of the Witwatersrand. It reads in a set of DNA sequences (typically ESTs or mRNAs) in FASTA format and organises them into clusters of similar sequences, producing a list of clusters and their members on standard output.
