annotateCTSS {CAGEr} | R Documentation

## Annotate and compute summary statistics

### Description

`annotateCTSS` annotates the CTSS of a CAGEr object and computes annotation statistics.

`annotateConsensusClusters` annotates the consensus clusters of a CAGEr object.

### Usage

    annotateCTSS(object, ranges)

    ## S4 method for signature 'CAGEset,ANY'
    annotateCTSS(object, ranges)

    ## S4 method for signature 'CAGEexp,GRanges'
    annotateCTSS(object, ranges)

    annotateConsensusClusters(object, ranges)

    ## S4 method for signature 'CAGEset,ANY'
    annotateConsensusClusters(object, ranges)

    ## S4 method for signature 'CAGEexp,GRanges'
    annotateConsensusClusters(object, ranges)

### Arguments

`object` | A `CAGEexp` object (`CAGEset`s are not supported).
`ranges` | A `GRanges` object, optionally containing `gene_name`, `type` and `transcript_type` metadata.

### Value

`annotateCTSS` returns the input object with the following modifications:

- The Genomic Ranges of the `tagCountMatrix` experiment gains a `annotation` metadata column, with levels such as “promoter”, “exon”, “intron” and “unknown”. If the annotation has a `gene_name` metadata, then a `genes` column is also added, with gene symbols from the annotation.

- The sample data get new columns, indicating total counts in each of the annotation levels. If the annotation has a `gene_name` metadata, then a `genes` column is added to indicate the number of different gene symbols detected.

`annotateConsensusClusters` returns the input object with the same modifications as above.
