blocks-methods: Get blocks/exons
In rtracklayer: R interface to genome annotation files and the UCSC genome browser

Description Usage Arguments Value Author(s) See Also

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

1	blocks(x, ...)

`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

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.

Michael Lawrence

import.bed for importing a track from BED, which can store block information; asBED for coercing a GenomicRanges into a BED-like structure that can be passed to this function.
