Hello, I want to extract a random sample (without replacement) of 7.5 million fastq sequences from illumina sequencing data that contains about 30 million sequences each in of the reads. I want to extract the same sequence from each of the two files ( e.g., if I extracted sequence no. 31 from read 1, I would want to extract the same sequence from read 2 also). How can I do this? Is there a script or module I can use? Any help would be appreciated. Thanks
