I am attempting to determine false positive/negative of various alignments and want to add a unique sequence identifier onto each fastq file.
I have ten genomes which I have synthetically sequenced (so 20 fq files). The current sequence identifiers look like this:
I want to change it so that it looks like this
Each of the ten genomes will have a sequence identified 1-10. I have tried reading about how to do this with awk but don't seem to understand the program.
