small RNA学习(二):原始数据去3'端adapter 小RNA测序的数据要多看一下adapter。 图片来源:https://www.plob.org/article/2810.html 拿我下载的数据来看,reads读长是51,但小RNA的长度基本都是20多点(21,24),肯定会把接头序列也测到。所以在很多地方都会强调要去除3'端的接头序列。 那接头序列怎么确定呢? 最...
RNA 3’ Adapter (RA3), part: 5’-AGATCGGAAGAGCACACGTCT-3’ fastp提示:AGATCGGAAGAGCACACGTCTG 为了找到高通量测序结果中adapter在reads中的位置,grep结果可以突出显示目标字符: 代码: zcatH-CK-1-3_raw.fq.gz|head-n100|grep'AGATCGGAAGAGCACACGTCT' H-CK-1-3_raw.fq.gz为未去adapter序列的原始下...
The quality of the small RNA libraries was first evaluated using FastQC v0.11.5 software (Figure 2). The most important metrics checked were the overall sequence quality: mean of phred quality per base and per read greater than 30; the GC percentage distribution per read: the data (red curv...
nf-core/smrnaseq is a bioinformatics best-practice analysis pipeline used for small RNA sequencing data. The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It comes with docker containers making installation trivial ...
Single-cell RNA sequencing (scRNA-seq) analysis was employed to investigate the presence of distinct cell subsets in the tumor microenvironment. InferCNV was used to identify cancer cells. Pseudotime trajectory analysis revealed the dynamic process of breast cancer angiogenesis. We validated the function...
FastQC anal- ysis (www.bioinformatics.babraham.ac.uk/projects/fastqc/) was completed to ensure quality of small RNAseq data. Bioinformatics. The three groups of EVs (small, medium and large) were analyzed in biological triplicates giving nine samples in total. After 3′ adapter removal,...

The quality of the raw sequencing reads was first confirmed with FastQC v0.11.7 (ref. 57). Next, RNA-seq reads were trimmed on the 3′ ends to remove the Illumina adaptor (AGA TCG GAA GAG CAC ACG TCT GAA CTC CAG TCA C) using Cutadapt 3.0 (ref. 58) with a minimum read ...
Step 1, the sampled data as mdRNA-Seq and metaRNA-Seq are used as input and both are quality controlled in Step 2 using FastQC and in Step 3 become trimmed and barcode/adapter removed using Trimmomatic (Bolger et al., 2014). Step 4, the modified data are transferred from FASTQ to ...
Small RNA ( < 200 nt) was isolated using the mirVana miRNA isolation kit (Ambion) according to the manufacturer's instructions. Small RNA was dissolved in the elution buffer provided in the mirVana miRNA isolation kit (Thermo Fisher Scientific) and submitted to BGI for HiSeq Small RNA library...
