Hi Djamel, Thanks for the detailed instructions. This type of "how-to" is extremely useful to those of us without local "experts" to rely on. One question: When you talk about commiting to the database, are you working with the main brahms DB, or a local copy? If you changing the main DB, isn't there a risk of someone messing up a good calibration that is already there? So far I have only "taken" from the DB so I'm not sure of protocols for modifying it.
