"WebPoly-G Trimming. Poly-G artifacts appear on two-channel sequencing system when the dark base G is called after synthesis has terminated. This results in calling several erroneous high-confidence G bases on the ends of affected reads. For contaminated samples, a large number of affected reads can be mapped to reference regions with high G content. " - Trimmed reads
