<p>I&#39;m new in this field. I want to identify circular RNAs from RNA-seq. I want to know which tools I could choose to detect circular RNAs using some simple commands. Thanks!</p>

You could try [CIRCexplorer][1], a combined strategy to identify junction reads from back spliced exons and intron lariats using TopHat and TopHat-Fusion. The commands are very simple. For more information. please refer to [**Zhang et al., Complementary Sequence-Mediated Exon Circularization, Cell (2014), 159:134-147**][2]
