About Chewie-NS

Welcome

Chewie-NS is a web-based Nomenclature Server, based on the TypOn ontology, that integrates with the chewBBACA suite to provide a centralized service to download or update schemas, allowing the easy sharing of results, while ensuring the reproducibility and consistency of these steps.

Chewie-NS is developed by the Molecular Microbiology and Infection Unit (UMMI) at the Instituto de Medicina Molecular João Lobo Antunes and Faculdade de Medicina of Universidade de Lisboa.

Goals

With this service we have following main goals:

1. Providing a public and centralised web service to manage typing schemas.
2. Establish a common nomenclature for allele calling.
3. Ensure the reproducibility and consistency of wg/cgMLST analysis.

Integration with chewBBACA

The chewBBACA suite has integration with Chewie-NS that enables users to directly upload new schemas to Chewie-NS, download existing schemas and synchronize local and remote schemas from chewBBACA command line version, allowing an easier integration into high-throughput analysis pipelines.
