I am working on the genomic data of E. Coli. My sequence reads are of high quality, and I already removed the adaptors and overrepresented sequences. However, for all of my samples, I received a warning for "Per Sequence GC Content" in the FastQC tool, and for a few of my samples (around 2% of my samples), I received an error in this field. How should I deal with that? Should I remove the samples which have an error for "Per Sequence GC Content in FastQC"?
