About Wefold

What is CASP?

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to determine protein structures using only the sequence of amino acids of newly experimentally determined but as yet unpublished structures.

What is WeFold?

This site, http://wefold.nersc.gov, 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. If you have questions about WeFold or would like to participate please contact Silvia Crivelli.

Sampling. Will provide decoys/solutions generated with a metaheuristic search of the conformational space of proteins. Such conformational space will be defined by all values of the phi and psi angles of the backbone of the protein.
Solutions/decoys will be obtained by optimizing a coarse-grained physic-based potential developed in our group. Some articles related to our energetic approach are:
