Phix reads

Webb27 dec. 2024 · Removing PhiX without users having to think about it is a good idea. In a perfect world, bcl2fastq should remove all PhiX, but a small fraction of PhiX reads get assigned to samples. In my testing, it's usually between 0-100 reads per multiplexed sample, but I have had a few examples of several thousand reads mapping to PhiX. WebbIf the TailorMix Dual-Indexed PhiX barcodes are not included on the sequencing Sample Sheet, the PhiX reads will be parsed into a folder named “Unknown” or “Undetermined” along with any other reads with index sequences not defined in your sample sheet.
