使用USEARCH的-fastq_mergepairs命令来合并双端序列。基本命令格式如下: bash usearch -fastq_mergepairs forward.fastq -reverse reverse.fastq -fastqout merged.fastq 其中: forward.fastq 是正向序列文件。 reverse.fastq 是反向序列文件。 merged.fastq 是合并后的输出文件。 检查合并后的序列: 合并后的序列将保...
FASTQ filenames are often based on the sample identifier, e.g. SampleA_R1.fastq. If you specify -relabel @ then fastq_mergepairs gets the sample identifier from the FASTQ file name by truncating at the first underscore (_) or period (.). A period and the read number is added after ...
