title: small RNA of JEC21
design: Small RNAs from HiSeq deep sequencing cover almost every kind of RNA, including miRNA, siRNA, piRNA, rRNA, tRNA, snRNA, snoRNA, repeat associated sRNA anddegraded tags of exon or intron. By comparing our sequences with those in databases and picking out the overlap on genome location between our data and the databases, sRNAs can be annotated into different categories.
