Hi I used fastqc tool after running Afterqc tool but at the result I saw k-mer content parameter is absent. what could be the reason of it and how should i add k-mer content to analysis?

Which version of FastQC did you use ? AFAIK libraries barely never pass the k-mer content test and was not a mark of data quality. So maybe they removed the fonctionnality

Edit : Here, check the FastQC changelog : https://www.bioinformatics.babraham.ac.uk/projects/fastqc/

Disabled the Kmer plot by default

So, by default it's disabled (since 0.11.6). Look at the FastQC options the enable it

It seems easy but if you don't know the reason it would be a big problem, the problem is solved thank you a lot.
