One thing that TF has as part of its DNA is to be flexible. Method development is a complex process and we are always looking at ways to reduce the effort, but to give flexibility in our approach.

One page that has alot of power, but is over looked many times is the General Setting Page.

These settings are the general setting for properties in the method.

These settings overide the default settings in the Application and apply to the Method and consiquently all the data that is processed with the method. These settings can be changed in at both the Master and Local Method levels.

Two points to look at.

1) Mass precision – This applies to all the masses used in producing results. It does not apply to the reporting    properties of thethings like RT, or calcualted amounts.

2) Instrument Method Edit/Update – In the master method you have a copy of the selected instrument method, which the ultimate Master instrument method is located in the Xcaliber/Methods directory. When you select edit, you are editing the copy that is located in the Master Method folder. When you select update you are overwriting the changes you made in the Master Method Copy, to the ultimate Instrument Master method in the Xcaliber/Methods directory. When you use these button in the local method you edit the Local Method copy of the instrument method that was copied to the Local Method directory, and the update button copies those changes to the Master Method instrument method. This isolated the Ultimate Master instrument method from batch level changes that you may not want to be inherited by other Master Methods produced in the furture.
