Depending on the
sample pattern wrong
peaks can get
assigned as marker if
running very close to
the actual marker.
Use the Aligned button in the TapeStation
Analysis software to detect the correct
markers. Compare to aligned/unaligned data
of good and questionable samples; and then
assign correct markers by right-clicking.
