The Count column shows the number of genes in the module that are enriched for each pathway. The GeneRatio column shows the proportion of genes in the module enriched for a given pathway out of all the genes in the module enriched for any given pathway. The BgRatio column shows the proportion of genes in a given pathway out of all the genes in the gmt file. For more details, please refer to the `clusterProfiler` package documentation.

### Examples

    # Get example CEMiTool object
    data(cem)
    # Read gmt file
    gmt <- read_gmt(system.file('extdata', 'pathways.gmt',
                       package='CEMiTool'))
    # Run module overrepresentation analysis
    cem <- mod_ora(cem, gmt)
    # Check results
    head(ora_data(cem))
