[求助] miRNA高通量测序分析时拷贝数的选取问题

分析高通量测序的miRNA数据时,通过质控的序列在进入后续分析(conserved,novel等的分析预测)时,对拷贝数(count数)有没有要求?
我在文献中看到有人全部拿去分析,有人去除了单拷贝,还有人甚至只用10拷贝以上的序列。
欢迎指教、讨论!

miRBase有这样的建议:
(1) Multiple reads (10–20 are commonly used cutoffs) support the presence of the mature microRNA (preferably from multiple independent experiments);
(2) The reads map to an extended sequence region (e.g. an assembled contig), and the sequence
flanking the putative mature microRNA folds to form a microRNA precursor-like hairpin with strong pairing between the mature microRNA and the opposite arm. Reads that map very many times
to a genome sequence should be discarded;
(3) Mapped reads do not overlap other annotated transcripts (i.e. there is no evidence that the short readsmay represent fragments of mRNAs or other known RNA types);
(4) Reads mapping to a locus support consistent processing of the 5'-end of the mature sequence (for example, the majority of reads overlapping a given mature microRNA annotation should have the same 5'-end; the 3'-end may be significantly more variable); and
(5) Ideally, reads will support the presence of mature sequences from both arms of the predicted hairpin (so-called miR and miR* sequences), and the putative mature sequences should base-pair with the correct 3'-overhang.

我一般取5个reads以上的
或者取TPM>1的
