I think you don't need to set up alias' anymore since hps-detectors is included in the hps-java jar now…is this right?

But you will have to set up an alias for this detector to make sure you pick up the new, incommensurate geometry. Otherwise you will either pick up the locally cached version or the official version from the web. I don’t recommend doing this unless you REALLY know what you are doing. If you want to conduct a study with the new field value in both the simulation and the reconstruction, then, as Matt has already pointed out, you should change the detector name. You will also need to set up an alias to point to this new detector. If you let us know the object of your analysis we can help you further.

If so, is that the only change that I need to make? Thanks!
