We strongly recommend that you first submit a couple of samples and wait for results before you scale up. That way you know you're not wasting money, and we don't waste machine time, on samples that require tweaking. In fact, if you try to submit many samples from a new experiment, we will require that you first pick two samples to be run, and then the rest of them after we know that they're good. This is in everyone's interest!

To minimize the number of reruns and to maximize the chance that you will get good data, we require a certain minimum concentration of the submitted sample and certain ways to measure it (see "Requirements" on the How to Submit page). We will not accept a sample that does not meet those requirements.


The folks at the SCGPM who are actually doing the sequencing (Ghia Euskirchen's team) do their best to give you large amounts of good data. Sometimes something goes wrong, and if it it does they'll redo things and you may not even notice. But sometimes the library isn't really up to par, or the concentration is way off, and adjustments would be required. At that point we'll ask you if you want to run another lane, but we'll have to charge you if you want the rerun.

Turnaround and priority

Users affiliated with the Cancer Center and with departments that contributed funds for machines have priority, but this priority will only be invoked if there is a substantial backlog. Turnaround varies with types of sample and circumstances out of our control, so we cannot guarantee specific timelines at this point. Please read "Bear in Mind" below.

Bear in Mind

The people at the SCGPM do their best. They process hundreds of samples every week. We serve more than 30 labs. Sometimes something goes wrong.

Our goal is to get you a high amount of high quality data, but there is variance. If you get one killer run, don't expect all runs to look like that.

Things take some time. We may let samples accumulate for a few days because each sequencing run is best performed with a diversity of samples and sources, which control for one another. Then, clustering and sequencing takes a while, and raw data analysis adds a few days. In the end, even if things work smoothly without issues, things can take a total of three weeks before you have data.


The submitter should talk to Ziming in a nonconfrontational way and if that does not resolve it call Arend.
