WebExtremely high nucleotide bias can be a sign of trouble, short stretches with high bias can be caused by the presence of linkers, barcodes or adapter contamination. There is usually some minor bias in the first 11-13bp of RNA-seq data due to not-quite random hexamer sequence priming but this bias is accounted for in the downstream analysis. Adapter contamination will lead to NGS alignment errors and an increased number of unaligned reads, since the adapter sequences are synthetic and do not occur in the genomic sequence. There are applications (e.g. small RNA sequencing) where adapter trimming is highly necessary.
