miRNA_MatureToPrecursor {miRBaseConverter} | R Documentation

## Convert the mature miRNAs to the corresponding precursors

### Description

This function converts the mature miRNAs to the corresponding precursors in the specified miRBase version.

### Usage

    miRNA_MatureToPrecursor(miRNANames, version = NULL)

### Arguments

`miRNANames` | A character vector representing the miRNA names.
`version` | The default is NULL representing the most possible latest version of the input miRNA Names will be checked automatically. Otherwise, a character value representing the version corresponding the input miRNA Names. Users can apply the function getAllVersionInfo() to get the available miRNA version names. The optional values are in below: "v6","v7_1","v8","v8_1","v8_2","v9","v9_1","v9_2","v10","v10_1","v11","v12","v13","v14", "v15","v16","v17","v18","v19","v20","v21","v22"

### Value

A data frame(nx2). The number of rows equal to the input miRNA Names. The two columns are defined as below:

- OriginalName : The input miRNA Names.

- Precursor : The corresponding precursors of the mature miRNAs.
