The five quality control (QC) metrics every NGS user should know

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. WebbThis means about 70% contigs were contaminated! I was curious about the percentage of contaminant lengths of each read. Then I used a simple Python script to count that.. Then I used R to visualize the relationship between contig lengths and the contaminated lengths. There were 14846 contigs, among which 12004 (80.86%) contigs, 2788 (18.78%) contigs …
