Hi,
Can anyone here explain what is mate unmapped and read unmapped?
Thanks!

Hi
I guess you are wondering about the bitwise flag of the SAM file (second field)
read unmapped means that that read is not mapped. the aligner does not know where to put it
mate unmapped means that the mate read (in a paired end sequencing) is unmapped.
At least this is my understanding.
hope this helps

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
