Confusion in SRA submission

Hello,

I am downloading an SRA data for a study. The study is basically, Illumina Paired data. However, the study description shows that, "This run has 2 reads per spot" and Reads section show the following:

Reads (separated)

>gnl|SRA|SRR768721.1.1 HWI-ST0798_0099:2:1101:1545:2240 (Biological) CCAGAATGCGCCCGGTGCATTCTGGGACTCCGAATCAGAAGAGGGAGTTGCGTCAGAGGC GGAGGTGGATGAAGCAGCGGGAGGAGAGGCGGAATCATCGG

>gnl|SRA|SRR768721.1.2 HWI-ST0798_0099:2:1101:1545:2240 (Biological) TACACTCGTAACCTCCTCGCCGCCAACCCCGACGTTCTTCAAGAGGGTGGTGCCATTGAC CTAAGCTCAATGTCCAGCNCNNNNNNNNNNNNNNNNNNNNN

Does this mean that, .1 & .2 represent the pairs and I should 'fastq-dump --split-files' to split them into two files ?

Thanks in Advance,

AP

That is correct. I suggest you make your task easy and download the fastq files from ENA here. No sratoolkit needed.

Always check ENA to see if fastq's are available. They generally are except for recent SRA submissions (which eventually appear).
