From: RNA-QC-chain: comprehensive and fast quality control for RNA-Seq data
The workflow and functions of RNA-QC-Chain. Firstly, reads with sequencing quality defects are trimmed by Parallel-QC, secondly, internal (ribosomal RNA) and external (non-target species) contaminations are identified and filtered by a tool called rRNA-filter. Finally, multiple statistics based on the alignment results are reported by a tool called SAM-stats
