Hello again,

I'm just doing some experimental work with a genome which features some "N" sequences. When I query the annotation, the k-mers with "N's" in them are not returned with any hits. For example if the sequence is "NCCCCCCCGGCGGCCACTCCTCCTCCCACCGGCGGCT", the k-mer "NCCCCCCCGGCGGCCACTCCT" doesn't return any hits but the rest of the sequences k-mers do. I've confirmed this sequence exists in the genome and so should have been annotated.

Is this expected behavior I need to work with or something erroneous?

I'm currently using the Python API.
