I like the visualisations in the GenomeGraphs package and would like to use it to plot RNA-seq data on a bacterial genome. However, that genome is not in the Ensemble database and therefore cannot be queried using biomart. Has anyone tried to use this package and create an annotation from scratch, e.g. given an EMBL file? Or is this feature eventually planned for the future? My best guess would be to provide an alternative implementation of the makeGeneRegion function, which takes an embl file instead of a mart object. Did anyone try this, or could the authors give a recommendation where to start?
