Removing fastq duplicates

WebFASTA and FASTQ formats are both file formats that contain sequencing reads while SAM files are these reads aligned to a reference sequence. In other words, FASTA and FASTQ are the "raw data" of sequencing while SAM is the product of aligning the sequencing reads to a refseq. A FASTA file contains a read name followed by the sequence. WebFASTQ files are named with the sample name and the sample number, which is a numeric assignment based on the order that the sample is listed in the sample sheet. Example: Data\Intensities\BaseCalls\samplename_S1_L001_R1_001.fastq.gz. samplename - The sample name provided in the sample sheet. If a sample name is not provided, the file …
