Our goal is to help advance the methods of identifying protein structure from sequence. The Center has been organized to provide the means of objective testing of these methods via the process of blind prediction. In addition to support of the CASP meetings our goal is to promote an evaluation of prediction methods on a continuing basis (note: not a resource).
This meta-server, named @TOME V2, allows one to submit an amino acid sequence to embedded softwares dedicated to homologous sequences search, structural predictions and fold recognition.
