Evaluation workshop of the first CAMI challenge


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

Critical Assessment of Metagenome Interpretation (CAMI)

Workshop Theme

The interpretation of metagenomes relies on sophisticated computational approaches, such as short read assembly, binning and taxonomic classification. All subsequent analyses can only be as meaningful as the outcome of these initial data processing methods. Tremendous progress has been achieved during the last years. However, none of these approaches can completely recover the complex information encoded in metagenomes. Simplifying assumptions are needed and lead to strong limitations and potential inaccuracies in their practical use.

The accuracy of computational methods in metagenomics has so far been evaluated in publications presenting novel or improved methods. However, these snapshots are hardly comparable due to the lack of a general standard for the assessment of computational methods in metagenomics. Users are thus not well informed about general and specific limitations of computational methods. This may result in misinterpretations of computational predictions. Furthermore, method developers need to individually evaluate existing approaches in order to come up with ideas and concepts for improvements and new algorithms. This consumes substantial time and computational resources, and may introduce unintended biases.

We suggest tackling this problem by a new initiative, aiming at the “Critical Assessment of Metagenome Interpretation” (CAMI). It should evaluate methods in metagenomics independently, comprehensively and without bias. The initiative should supply users with exhaustive quantitative data about the performance of methods in all relevant scenarios. It will therefore guide users in the selection and application of methods and in their proper interpretation. Furthermore, it will provide valuable information to developers, allowing them to identify promising directions for their future work. The first CAMI challenge took part in 2015. In the evaluation workshop of the first CAMI challenge at the INI, the challenge results will be analyzed and discussed with participating developer teams. In addition, the focus of future CAMI challenges will be discussed. All talks will be streamed. Interested scientists are encouraged to join.
