+abstract: >-
+  Given human (hg19 or hg38) or mouse (mm9 or mm10) based
+  genomic region sets (i.e., region sets) and/or (ranked)
+  gene sets of interest and respective background
+  region/gene sets, the enrichment of terms within the
+  configured databases is determined using LOLA, GREAT,
+  GSEApy (over-representation analysis (ORA) & preranked
+  GSEA), aggregated and visualized.
