CASP, Critical Assessment of techniques for protein Structure Prediction, is a community-wide, worldwide experiment for protein structure prediction taking place every two years since 1994. The experiment challenges computational scientists to determine protein structures using only the sequence of amino acids of newly experimentally determined but as yet unpublished structures.

This site, WeFold.org, is a science community gateway designed to bring together labs and individuals from all over the world for online discussion and collaboration during CASP. Started in April 2012, it has enabled the interaction among various groups that work on different components of the protein structure prediction pipeline thus making it possible to leverage expertise at a scale that has never been done before. The collaboration resulted in five different branches, each submitting their own models. In the next couple of weeks we’ll upload the abstracts that briefly describe those branches.
