The tRNA package allows feature information of tRNAs to be accessed and list of
tRNA to be subset based on these features. The main purpose is to unify
overlapping functions from the
[`tRNAscanImport`](https://doi.org/doi:10.18129/B9.bioc.tRNAscanImport) and
[`tRNAdbImport`](https://github.com/FelixErnst/tRNAdbImport) packages.
The functionality is currently under development and may change. The package
expects a `GRanges` object with certain columns as input. The following columns
are a requirement: `tRNA_length`, `tRNA_type`, `tRNA_anticodon`, `tRNA_seq`,
`tRNA_str`, `tRNA_CCA.end`. Outputs of `tRNAscanImport` and `tRNAdbImport` meet
these requirements.
## Installation
The current version of the `tRNA` package is available from Bioconductor.
```{r}
BiocManager::install("tRNA")
# Load and attach thepackage
library("tRNA")
```
## Functions
Have a look at the vignette for an overview of the functionality. Additional
functions are planned to be added in the future.
