It's hard to help without knowing what the issues are that you are
running into, so ... what's going wrong?
One way you could explore this question yourself is to use the larger
(324 piRNA) dataset that "went well" and simply take half of the data
from it and rerun the same analysis on the smaller set. Do you get
While you're playing with that idea, please provide a follow up email
with more specific details about what the issues are that you are
running into with your new (smaller) dataset.
