annots_from_fa_df {BUSpaRse} | R Documentation

## Get genome annotation from Ensembl FASTA file

### Description

Ensembl FASTA files for RNA contain much of the information contained in GTF files, such as chromosome, genome assembly version, coordinates, strand, gene ID, gene symbol, and gene description. Given such a FASTA file, this function can extract all the genome annotation information and return a data frame or a `GRanges` object.

### Usage

    annots_from_fa_df(file)

    annots_from_fa_GRanges(file)

### Arguments

`file` | Path to the FASTA file to be read. The file can remain gzipped.

### Value

`annots_from_fa_df` returns a data frame and `annots_from_fa_GRanges` returns `GRanges`.

A data frame with genome annotations.

### Examples

    fn <- system.file("testdata/fasta_test.fasta", package = "BUSpaRse")
    annots_from_fa_df(fn)
    annots_from_fa_GRanges(fn)
