I downloaded the paired-end SRP325386 dataset from SRA using the following command:

esearch -db sra -query SRP325386 | efetch -format runinfo | cut -d ',' -f 1 | grep SRR | xargs -n 1 ./../sratoolkit.3.0.0-ubuntu64/bin/fastq-dump --split-3 --gzip --skip-technical --readids -W --read-filter pass  

However, the runs that were downloaded were not split into two files. For each run, I only get one file each SRR*.fastq.

How do I get the paired ends in two separate files?
