02-quality-control: clarification for paired-end data

[youyaqi]

How could the content be improved?

The data are paired-end, so we will download two files for each sample (forward reads in xxx_1.fastq.gz and reverse reads in xxx_2.fastq.gz). We will use the European Nucleotide Archive to get our data. The ENA “provides a comprehensive record of the world’s nucleotide sequencing information, covering raw sequencing data, sequence assembly information and functional annotation.” The ENA also provides sequencing data in the fastq format, an important format for sequencing reads that we will be learning about today.
