I'm looking at some NCBI SRA datasets for Paired-End Illumina Rna-seq.
In each case, the dataset is made up of 3 fastq files, even though I would only expect 2 (one for each end).
Example:
SRR018256.fastq (2,048,908 lines)
SRR018256_1.fastq (50,313,152 lines)
SRR018256_2.fastq (50,313,152 lines)
All files look OK, and the _1 and _2 files have the same number of lines, as I would expect.
Does anyone have any idea what the third file might be?
Thanks.
