Hi, I recently recieved the fastq files from a sequencer service. This was an experiment with human cell lines and along with the sequences they gave me the next warning:
"we detected the presence of Xenotropic murine leukemia virus sequences in some of the samples, resulting in a higher than expected percentage of no matches in the mapping statistics."
Do you think I should remove these sequences form my reads before alignment? If so, how can I do it?
