Hi, I am having a problem with FastQC. When I view per base quality, it gives me a strange looking graph: [cid:2f881b69-b1f8-4c44-8f23-2cf3799bd703@fasmail.harvard.edu] I am wondering it this is because of a problem with my data? None of my colleagues have seen this before. Thanks! Justin

If you used the raw illumina fastq data (the txt file generated) file that means that your data quality is very low, the sample has been most likely contaminated. you can still run it just to see what it gives you.
