WebFASTQ files are mostly used to store short-read data from high-throughput sequencing experiments. The sequence and quality scores are usually put into a single line each, … WebAs a second exercise, try to generate a new file from the fastqz file containing every 1000th read. This is useful as subsampling is often needed to test software. Fastqc will take very long and a lot of memory if it needs to read in a giant file. It is thus better to subsample if you have large fastq files.
