title: S18
design: The pilot process follows the standard steps provided by Illumina, including preparing libraries and sequencing experiments. The small RNA sequencing library is prepared using TrueSeq Small RNA Sample Prep Kits (Illumina, San Diego, USA) kits. Once the library preparation is complete, the built library is sequenced using illumina Hiseq2000/2500, with a single-ended 1X50bp sequencing read length.
