  • How to parse FASTQ file?

    I am new in NGS. I need to format some fastq files. For example I want to replace characters /1 and /2 with -1 and - 2 in the files having data like @HWUSI-EAS1671_0001:5:1:1022:10290/1.
    I tried to do it in perl with pattern matching but the files are too big to parse. Could anyone please give me suggestion on share any code?
