I would like to know two things
1- why when I look at the ebi.uk for a sample, the fastq files are split in two part for each sample?
2- how to identify if a data is single end or paird reads?for example, I only know Illumina HiSeq 2000 (Homo sapiens). Is there a way to know that?
3- how to know if a the fastq is forward reads or reverse reads and why one should generate that?
