Estimates promoter counts and activity in a single command

proActiv(
  files,
  promoterAnnotation,
  fileLabels = NULL,
  condition = NULL,
  genome = NULL,
  ncores = 1
)

`files`	A character vector. The list of input files for which the junction read counts will be calculated
`promoterAnnotation`	A PromoterAnnotation object containing the intron ranges, promoter coordinates and the promoter id mapping
`fileLabels`	A character vector. The labels of input files for which the junction read counts will be calculated. These labels will be used as column names for each output data.frame object. If not provided, filenames will be used as labels. Defaults to NULL
`condition`	A character vector. The condition to which each sample belong to. Must correspond to the order of the files. If supplied, results are summarized by condition. Defaults to NULL
`genome`	A character. Genome version. Must be specified if input file type is a BAM file. Defaults to NULL
`ncores`	A numeric value. The number of cores to be used for counting junction reads. Defaults to 1 (no parallelization). This parameter will be used as an argument to BiocParallel::bplapply

A SummarizedExperiment object with assays giving promoter counts and activity with gene expression stored as metadata. rowData contains promoter metadata and absolute promoter activity summarized across conditions (if condition is provided)
