WebAfter trimming with trimmomatic, some reads can be discared, and their mate become "unpaired". Usually, only a small fraction of the reads become unpaired, and they can be ignored. Alternatively, you can map them as single reads along with the remaining paired reads. Thanks, Carlo. So, in the case when there is not reads discarded ¿There is no ...
