Summary of sequencing data lactating mouse, bovine and AGO2 mammary gland miRNA libraries.

apoly-A stretches removed.b17–28 nt size filtering,reads used by miRDeep2 quantification process.creads with at least one and at most five reported alignments, used by the miRDeep2 prediction process.* In AGO sample 2, many reads below 10 counts were present, subsequently discarded by miRDeep2 processes.

已移除聚腺苷酸（poly-A）序列片段；对长度介于17至28 nt的序列完成长度筛选。用于miRDeep2定量分析流程的测序读段（reads）需满足至少1个且至多5个已报道比对匹配的条件，此类读段将被用于miRDeep2的预测分析流程。* 在AGO样本2中，存在大量计数低于10的测序读段，后续被miRDeep2分析流程过滤丢弃。
