blocks-methods {rtracklayer} | R Documentation

## Get blocks/exons

### Description

Obtains the block ranges (subranges, usually exons) from an object, such as a `GRanges` imported from a BED file.

### Usage

    blocks(x, ...)

### Arguments

`x` | The instance from which to obtain the block/exon information. Currently must be a `GenomicRanges`, with a metadata column of name “blocks” and of type `IntegerRangesList`. Such an object is returned by `import.bed` and `asBED`.
`...` | Additional arguments for methods

### Value

A `GRangesList` with an element for each range in `x`. The original block ranges are relative to the start of the containing range, so the returned ranges are shifted to absolute coordinates. The seqname and strand are inherited from the containing range.
