We operate on a first in, first on basis for our investigators. However we cannot always control the SPEED at which the queue moves forward. We need to fill all the space on high-throughput flowcells. If instruments are not performing up to spec, they are taken off-line and serviced to ensure you receive quality data. When there are issues related to infrastructure, computing, instrument failure, power failure, etc. and we need to reset a run, this also delays the queue. The lab staff cannot change the queue, so please don't ask them.
