# MRC-CLIMB_Workshop_Gambia
This repository represents a showcase of Jupyter Notebooks, presented during the CLIMB-BIG-DATA Bioinformatics Workshop at the MRC Unit in The Gambia. The workshop took place in the MRC Unit in Fajara between the 13th and 17th of November 2023.
## Publication
Genomes and reads associated with this show-case tutorial is linked to the following publication: "Gene pool transmission of multidrug resistance among _Campylobacter_ from livestock, sewage and human disease" published in Environmental Microbiology (doi:10.1111/1462-2920.14760). All sequence data are linked to NCBI BioProject PRJNA528879. The bacterial genomes are available in GenBank under accession codes SRX5575129 to SRX5587545.
## Files Summary
The files include data for 169 isolates representing a collection sampled from human clinical cases, animals and sewage: Each directory contains the following:
* **Raw_Reads**: directory with raw reads data (currently available on NCBI BioProject PRJNA528879 - will be available on figshare)
* **Assemblies**: directory with assemblies (available on figshare)
* **Core_alignment.fas**: Core alignment of 169 assembled genomes (available on figshare)
* **Phylogeny.nwk**: Maximum-likelihood tree reconstructed by FastTree
* **Metadata.csv**: Genome metadata .csv file used for visualization
* **Figshare_DOI.txt**: File with doi links to data repositories in figshare
* **Antimicrobial_resistance_PA.xlsx**: Presence absence of AMR genes
