Good evening all,
I have prepared (ds)cDNA from viral RNA extracted from plasma that was subsequently sequenced on a MiSEQ following standard library preparation.
When I got the reads back, I only have TTTTTTTTTTTTTT or AAAAAAAAA sequences for 99.9% of my reads. Read have good phred score and are of the expected length (100 bp).
Any ideas about why I might get such a result?
Thanks!
Nicolas
