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 lanes on multi-lane flowcells. If instruments are not performing up to specs, they are taken off-line and serviced (otherwise you get bad data). When there are issues related to infrastructure, computing issues, 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.
