Data Analysis: Reprocessing data

In contrast to data review, sequence reprocessing means that all the runs of a

sequence are reanalyzed in the sequence context, i.e. including calibration

table updates, parameters changes in the sequence table, additions of new

methods to the sequence, etc.

With the new data organization concept, the sequence container includes all

files needed for reprocessing: the data files, a copy of the sequence file, and all

the sequence methods originally employed with the acquisition. Thus, in order

to reprocess a sequence you simply have to load it into the Navigation Table

and the required tool set is available.

Note the following rules with regard to reprocessing:

• All actions are performed on the sequence methods. If changed analysis

parameters are to be applied, you have to change the sequence methods.

• The method loading settings of the Preferences dialog have no influence on

reprocessing; it always works on the sequence methods or updated

sequence methods. This feature set is valid for reviewing only.

• During reprocessing, the Batch (*.b) file, the sequence/single run log (*.log),

the Navigation Table, and the individual data analysis method (DA.M) of

each processed data file are updated.

• If you want to add new methods from one of the master method directories

to the sequence table, you have to use the Browse item in the list of

methods to browse to any specified method directory (only the methods

already in the sequence container are available without browsing). The new

method is also copied to the sequence container during reprocessing. This

implies that you cannot select a method with the same name as a method

already present in the container.
