 ### Predict tRNA and tmRNA sequences
 
-The [MIMAG](https://www.ncbi.nlm.nih.gov/pubmed/28787424) standard specifies that in order to reach particular quality criteria, a MAG must contain a certain number or tRNA sequences. We can search a MAG or genome for these using `Aragorn` ([link here](http://130.235.244.92/ARAGORN/)).
