Fastqc sequence duplication levels
Our informatics group recently started to use fastqc. I am seeing high (70%) sequence duplication for TruSeq mRNA-Seq libraries. These are from a single lane of a 51 bp read on Illumina's HiSeq 2000. I also see ~30-40% duplicates from a exon cature run. Is this normal? I am concerned that it is way too high.
