WebFASTQ format is a text-based format that stores biological sequence (generally nucleotide sequence) and its corresponding Phred quality scores in a single file. It is a widely used format in the sequence analysis as it contains much more information than FastA; it is required by many analysis tools. WebPreprocessing and mapping reads Raw fastq files first need to be preprocessed, extracting any elements that are a part of the sequence read and potentially “cleaned” with applications such as HTStream.
