The long-term dynamics of IS elements and their effects on bacteria are poorly understood, including whether they are primarily genomic parasites or important drivers of adaptation by natural selection. Here, we investigate the dynamics of IS elements and their contribution to genomic evolution and fitness during a long-term experiment with Escherichia coli. This data set includes the Rmd file to analyze the genomic and metagenomic data (Tenaillon et al. 2016 and Good et al. 2017) in light with the IS dynamics and their correlation with fitness improvements described in the present work. 

This data set includes and RMD file containing metadata, markdown-formatted plain text and code. For further information on methods, please refer to the paper.
