It is possible to extract sample annotations using `getAnnotation` function. One can also extract the scaled retention levels of the introns/exons using `scaledRetention()` function. Notes that `colData` and `rowData` methods of `SummarizedExperiment` class can also be used to extract row and column data.

### Usage

    getAnnotation(x)
    scaledRetention(x)

### Arguments

`x` | Object of type `SummarizedExperiment`.

### Value

    head(scaledRetention(mdsChr22Obj))

    #for row and column data SummarizedExperiment methods can be used
    head(rowData(mdsChr22Obj))
    colData(mdsChr22Obj)
