 * Note that Roadmap queries requires `tabix` to be installed on your machine, or within a conda environment (`conda_env = "echoR"`). 
 * Parallelizing these queries across multiple thredas speeds up this process (`nThread=<n_cores_available>`), as does reusing previously stored data which is automatically saved to the locus-specific subfolder (`<dataset_type>/<dataset_name>/<locus>/annotations/Roadmap.ChromatinMarks_CellTypes.RDS`).
