This tool validates a FASTQ file. When data is paired it can also validate a pair of FASTQ files. ValidateFastq will check if the FASTQ is in valid FASTQ format. This includes checking for duplicate reads and checking whether a pair of FASTQ files contains the same amount of reads and headers match. It also check whether the quality encodings are correct and outputs the most likely encoding format (Sanger, Solexa etc.).
