CAGI Scientist Opening: apply here ☀️

CAGI3 Challenge

All challenges have now closed for submissions. The deadline for most prediction submissions for the CAGI 2013 challenges was 25 April 2013 at 11:59 pm PDT.


The Critical Assessment of Genome Interpretation (CAGI, \'kā-jē\) is a community experiment to objectively assess computational methods for predicting phenotypic impacts of genomic variation and to inform future research directions. In this assessment, participants are provided genetic variants and make predictions of resulting phenotype. These predictions are evaluated against experimental characterizations by independent assessors. The CAGI experiment culminates with a community workshop and publications to disseminate results.

The Experimental Goals are:


The acquisition of large numbers of personal genomes has long been the aspiration of genomics researchers, and sequencing technologies promise to make this affordable within the next several years. Already, large-scale genotyping arrays are widely used in research and retail DNA tests of genetic markers have captured the public’s imagination. Unfortunately, personal genomes presently have limited research, or medical value due to a variety of scientific, technical, legal, sociological, and ethical challenges. Yet, whole genomes are also providing tremendous breakthroughs in basic science, such as revealing the genetic basis of Mendelian diseases that had proven refractory to traditional genetics for decades, and helping to unravel the mechanisms by which cancer emerges and evolves.

The CAGI experiment is timely and of wide relevance because of the burgeoning availability of individuals’ genomes, and the desire to interpret them for research and clinical applications. Currently, the field lacks a consensus on the absolute and relative suitability of the panoply of different methods for prediction of the phenotypic impact of genomic variation. The results from CAGI will help the broader community understand the appropriate level of confidence they should have in variant prediction methods, and which classes of approaches are most suitable to a particular application.

CAGI follows in the spirit of the long-running Critical Assessment of Structure Prediction (CASP). Organizers are in the process of collecting unpublished genomic data with associated phenotype characteristics. During the prediction season, participating groups will submit predictions in these areas based on data provided. The prediction accuracy will be evaluated by assessors and results will be revealed at the CAGI conference.

The CAGI 2013 Conference took place 17 - 18 July 2013 at the Max Planck Institute for Molecular Genetics in Berlin, Germany. This year's The CAGI 2013 results are now posted. The conference program page contains the full set of slides that were presented at the meeting. The abstract book contains abstracts describing the prediction methods. Each challenge page has the slides for talks given for that challenge as well as the challenge's answer key, assessor summary, and predictions.

The Challenges and Assessors

The 2013 prediction season ended on 25 April 2013. The meeting to discuss the results will be held in Berlin, 17-18 July 2013 (the two days preceding the ISMB SIGs).
