Hi. I have some Phragmites RNA seq data. I tried to use Skewer to trim the adapter of these reads, as the code " skewer-master/skewer -m pe -l 50 Phragmites_RNA/raw_data/PL_R1.fastq Phragmites_RNA/raw_data/PL_R2.fastq -o Phragmites_RNA/raw_data/skewer/PL" After trimming, I run fastqc of these trimmed data to check the qualities. I found all these data have the kmer flag and position either on the front or the end position. However, the adaptor section did not give me the flag. I am wondering what cause these kmer issues and do I need to worry these for my downstream analysis. Or parameter setting of the skewer is wrong?
