I have run a FASTQC analysis and found out that there are hundreds of over-represented sequences in my datasets. Some of these, are Illumina PCR primers, some are single end adapters.
Does it mean I have some contamination going on? What can I do about it? Do I simply remove the primer and adapter sequences or what else?
Thanks in advance.
